The peanuts planted in the fields of our farmer friends: the flowers grow too weak and too poor, and naturally they cannot achieve high yields, but they cannot achieve high yields if they grow too vigorously and too quickly; When flowering and podding are in place, the ground is too wet or too dry, the podulation rate of fruit needles into the soil is too low, water and fertilizer management is not in place, and serious pests and diseases occur, so peanuts cannot achieve high yields.
Today's article, agricultural technology basket will give you a talk from the peanut field fertilization management: how to ensure stable production of peanuts through fertilization, compete for high yield, we plant peanuts farmers and friends may wish to peanuts a few minutes to take a look at and learn, peanut fertilization and production management is very simple - focus on the "three chasing and one spray" fertilization method.
1. Light seedling fertilizer to promote growth and branching
After we sow peanuts into the ground, wait until the peanut seedlings emerge to the group of seedlings to grow and branch during this period of time, there is a situation such as slow seedling growth, small seedlings, poor growth, etc., at this time you can grow to three or five leaves, each mu to it to properly apply some fertilizer with high nitrogen content, such as about 20 kg per mu of high nitrogen, phosphorus and low potassium compound fertilizer (nitrogen-containing fertilizer) or 6-10 kg of urea per mu, so that you can make your original peanut seedlings that are not growing well to speed up the growth rate. Enhance the ability of branch growth and ensure the smooth differentiation of flower buds, so as to lay a good foundation for the smooth flowering, needle drop and pod formation of peanuts.
However, we need to pay attention to: after the peanut seedlings emerge to the flowering and fruit drop needle, if the water and fertilizer in the ground is sufficient and the peanut seedlings grow normally, then the peanut does not need to chase the seedling fertilizer again, if you chase the fertilizer again in the case of normal flower growth seedlings, or too much topdressing at the seedling stage, it will stimulate the peanut seedling branches and leaves to grow excessively and affect the normal flowering and podding of peanuts (that is, easy to reduce yield).
Second, skillfully chase flowers and fertilizer to promote flowers and pods
When peanut falls from flowering to poding, the demand for various fertilizer nutrients will increase greatly, and the branch growth and flowering and podding are carried out simultaneously, and the insufficient fertilization will directly cause peanut to bloom less, fruit needles and pods less, resulting in the later yield reduction of peanut. Therefore, in order to ensure that peanuts can bloom and set pods smoothly, our farmers generally need to catch up with fertilizer before peanuts bloom and fall needles, so as to increase nutrition for peanuts and promote the smooth flowering and fall of peanuts to form fruit pods.
Isn't it nice to have peanuts blooming?
When topdressing before peanut flowering, the most beneficial fertilizer for peanuts to flowering and podding at this time is a fertilizer with high phosphorus and high potassium and medium nitrogen (suitable for peanut land with vigorous growth), or a fertilizer with the same amount of nitrogen, phosphorus and potassium content (suitable for peanut land with normal growth or weak growth), generally at this time, combined with peanut root soil, about 30 kg of compound fertilizer per mu can be applied (if water-soluble fertilizer is used with water, 5-6 kg of water-soluble fertilizer of large elements can be applied per mu). Note: Root soil fertilization can not only increase nutrients for peanuts and improve the flowering and podding rate of peanuts, but also help the fruit needles on peanuts to enter the soil more smoothly and improve the flowering pod-forming rate.
3. Heavy chasing fruit fertilizer to expand the fruit pods
After the peanut is put into the soil to form a young pod, at this time the peanut needs to continue to grow vigorously branches and leaves, on the other hand, it is necessary to let the underground tender fruit pods expand and develop rapidly, so this time is the critical period when the peanut needs sufficient fertilization during the whole growth period, if the fertilization can not keep up with or the fertilization is unreasonable at this time, it is not only easy to cause the growth of peanut seedlings to weaken and deteriorate and affect the concentrated and rapid expansion and granulation of the underground fruit pods, but also will easily lead to a large number of peanut underground fruit pods to expand slowly, empty pods and small grains, empty shells, deflated grains, rotten fruit pods and other problems.
When topdressing in the peanut pod expansion period, at this time, it is not only necessary to reduce the use of nitrogen fertilizer to control the vigorous growth of above-ground branches and leaves, but also to increase potassium fertilizer, phosphate fertilizer and calcium fertilizer to promote the rapid expansion of fruit pods and saturate the grains, especially in the peanut flowering after the formation of underground fruit pods until the peanut is ripe and harvested during this period of time, the agricultural technology basket reminds everyone to pay attention to the peanut calcium fertilizer, which is very important, and is often ignored by most farmers and friends.
Normally speaking, after all the flower needles of peanuts fall into the soil to form fruit pods, wait until the young pods begin to expand in the ground, at this time it is most appropriate to start topdressing the fruit pod expansion fertilizer for peanuts, and it is recommended to apply 30-40 kg of high potassium and low phosphorus and low nitrogen fertilizer per mu (normal peanut land) or use high potassium and high phosphorus type (peanut land with strong growth) and balanced fertilizer (peanut land with weak growth), At the same time, an additional 30-40 kg of calcium fertilizer (such as superphosphate or calcium, magnesium, phosphate fertilizer, etc.) is applied to each mu of peanut land. If you are willing to spend money to use water-soluble fertilizer, then at this time, topdressing can also be combined with watering to apply 10-12 catties of nitrogen, phosphorus and potassium macro-element water-soluble fertilizer per mu, and apply 2 times in a row, the first time to apply a large number of elements of water-soluble fertilizer with high nitrogen, high phosphorus and high potassium, and the second time to apply a large number of elements of low-nitrogen, phosphorus and high potassium, every 15 days or so (water-soluble fertilizer can be applied once at most, which can ensure that peanuts do not lack fertilizer nutrients within 15-20 days).
Fourth, skillfully spray foliar fertilizer to improve production and quality
For most peanut fields, as long as the above three times of soil fertilization are applied in the process of peanut planting, basically even if the fertilization is in place, the smooth and stable yield of peanuts can be realized. But if you want your flowers to grow better, get a higher yield per mu, and achieve a fuller and fuller single weight of fruit pods, then the agricultural technology small back basket recommends that you follow the following method to apply foliar fertilizer to peanuts several times at the appropriate time node, because the rational use of nitrogen, phosphorus and potassium fertilizers for planting peanuts can ensure basic growth and basic stable yield, and the clever use of foliar fertilizer for peanuts is possible to further improve the yield per mu of peanuts and improve the quality of peanuts.
(1) Peanuts prefer calcium fertilizer and molybdenum fertilizer, and calcium and molybdenum supplementation should be given to peanuts, which can promote peanuts to obtain higher yield and quality. At the same time, peanuts often suffer from lack of magnesium fertilizer, iron fertilizer, zinc fertilizer, and boron fertilizer and reduce yield due to deficiency symptoms (such as yellow leaves, white leaves, small leaves, viral diseases, leaf lesions, rotten pods, and empty shell deflated grains), so planting peanuts should appropriately supplement some fertilizers containing magnesium, iron, zinc, and boron, so as to supplement the full nutrients for peanuts to achieve the purpose of increasing yield and income of strong seedlings, protecting leaves, promoting fruits, and increasing weight.
(2) The best and fastest way to supplement peanuts with calcium, zinc, magnesium, boron, zinc, iron and other medium and trace element fertilizer nutrients, even if the peanut is sprayed with foliar fertilizer containing the above nutrient elements, and the above-mentioned foliar fertilizer can be sprayed together with potassium dihydrogen phosphate at different stages to obtain better production and income increase effect.
(3) In the management of peanuts skillfully using foliar fertilizer to promote yield and income, the agricultural technology small back basket suggests that you (the following foliar fertilizer formula and spraying times are flexibly decided according to your actual planting situation):
(1) When the peanut seedling stage reaches the long branching of the tuanut tree, the whole field is sprayed once with ammonium molybdate (10-15 grams), chelated zinc (15-20 grams) and potassium dihydrogen phosphate (30-40 grams) mixed with water per mu.
(2) Before peanuts bloom to sporadic flowering in the ground, each mu is diluted with chelated calcium (15-20 grams), boric acid (15-20 grams, note that there is no chelated boron in foliar fertilizer), chelated magnesium (15-20 grams) with potassium dihydrogen phosphate (40-50 grams) diluted with water and sprayed once in the whole field.
(3) After the flower needles in the peanut field are put into the soil, each mu is diluted with chelated calcium (15-20 grams), chelated iron (15-20 grams) with potassium dihydrogen phosphate (50-60 grams) and brassinolide (6-8 ml) mixed with water and sprayed once in the whole field.
(4) During the whole expansion and saturation period of peanut underground pods, each mu was diluted with chelated calcium (15-20 grams) with potassium dihydrogen phosphate (60-80 grams) and brassinolide (8-10 ml) mixed with water and sprayed once in the whole field.
(5) Note: When mixing different foliar fertilizers, chelated foliar fertilizers must be used, and other conventional foliar fertilizers are easy to antagonize each other and inhibit absorption when mixed with other conventional foliar fertilizers, which directly affects the effect of foliar fertilizer use. In addition, when spraying foliar fertilizer for peanuts, we must avoid the period of high temperature and strong light at noon, and we also operate when spraying various fungicides, insecticides, herbicides, and growth regulators in the peanut field.
