The sun is gradually approaching the summer, and the night is born in the summer.
Today we have the tenth of the twenty-four solar terms, the summer solstice. There is a poem: the lotus leaves are infinitely blue, the lotus flowers are different red, and the arrival of the summer solstice also means that the hottest time of the year is about to appear, and this period is also a critical period for the management of millet fields.
How to lay a good foundation for a good harvest through scientific management? Xiaobian has specially sorted out the key points of field management of Zhangzagu for the reference and application of the majority of Zhangzagu growers.
First, the rain beat processing before the seedlings
After sowing, before the seedlings in the event of rapid rain or a long period of rain and water, the surface soil will be nailed to affect the emergence of seedlings, in the afternoon of sunny and hot days can be suppressed to break the nails and release seedlings; there are sprinkler irrigation conditions can spray water to release seedlings.
Second, check out the seedlings
7-15 days after sowing, the emergence of seedlings should be checked, and the emergence of poor seedlings should be remedied in time.
Third, the prevention and control of diseases and insect pests
Spray high chlorine + Avi (or Avi salt) at the emergence stage to control millet scale leaf beetle and pseudo-ground nail; pay attention to the prevention and control of insect pests such as drill heartworm and millet mud worm at the seedling stage, timely remove diseased plants such as white disease and bury them deeply, prevent the harm of armyworms and second-generation drill heartworms at the jointing stage to the ear extraction stage, prevent the occurrence of millet millet plague, smut rust and other diseases, and pay attention to the prevention and control of double-spotted firefly leaf beetles, blind bugs and other hazards during the filling stage to improve the quality and yield of millet.
Fourth, weeding
1. Select a suitable herbicide: 100 ml (1 vial) per mu with "ZhangZagu"; use herbicides of broadleaf herb as needed, you can choose 53% content of 2methyl 4 chlorine dimethylamine salt 30ml, or 56% 2 potassium 4 chlorine sodium soluble powder 30g, or 20% chlorofluoropyroxyacetic acid (emulsion) 100ml, or one or more of the herb pine 40g, mixed with water about 30L (kg) or about evenly sprayed on the ground. When there are more broad-leaved grasses and larger, spray broad-leaved herbicides first, and then spray "Zhang Weed Valley" to catch them when it withers some of the pointed grasses that expose the grass family. Too much grass can be appropriately increased, the amount of half-film millet can be halved, and the whole film can be used or used according to the situation.
2. Before the 4-7 leaf stage of the seedlings and the 4 leaves of weeds, choose a windless sunny day with an air humidity of more than 65%, and spray before 9 a.m. or after 5 p.m. without dew.
3. Do a good job of secondary dilution and dispensing to improve the use effect.
4. It is recommended to use electric or mechanical spray, good atomization and good effect.
5. Drive at a uniform speed throughout the whole process to improve the quality of spraying.
6. Do a good job of drift protection to prevent drug damage.
7. Clean the medicine barrel (jar) before dispensing to prevent other herbicide residues.
Fifth, medium cultivation and topdressing
The whole growth period of millet should be cultivated about 3 times to help improve the ground temperature, loosen the soil to promote growth, and the pregnant ear stage should chase 15kg of high nitrogen and low potassium fertilizer with the second medium cultivation mu.
Sixth, promote early puberty
In the later stage of millet grouting, potassium dihydrogen phosphate + urea, or other foliar fertilizers can be sprayed to promote the speed of millet filling and prevent lodging.
