September to October is the season for autumn garlic sowing. If garlic wants to have high yields, fertilization formula is the first. Many farmers have some misunderstandings when fertilizing, such as some new garlic areas, farmers do not know what kind of formula can be used to increase production? There are also some old garlic areas, planted all year round, the soil salinization is serious, do not know how to fertilize to improve?
Garlic has a long growth cycle, prefers fertilizer, and is resistant to fertilizer, and has high requirements for soil fertility. Therefore, the use of bottom fertilizer is very critical, and it should be sufficient when used. Many experienced growers fertilize according to the soil conditions. In addition, when fertilizing, there is also a big gap in the cost of input, and some farmers have a difference of 200 to 300 yuan in the bottom fertilizer input, and even there will be no profit.
Farmer Lao Liu has been planting garlic for more than ten years, he said: "My land, stubble is more serious, the amount of fertilizer is large, some phosphorus and potassium elements can not be absorbed, it is deposited into the soil." Now I use organic fertilizer plus chemical fertilizer for fertilization, and if I use chemical fertilizer alone, I also need to add biological bacterial fertilizer. Prevent soil compaction and salinization, and when the garlic grows, a large area of death occurs. ”
Many plots are heavy stubble planting, in the fertilization should pay more attention to some, generally what formula do you use? How many catties can be produced? "This year, I plan to use 2,000 pounds of manure, add chicken manure that has been decomposed from straw, and turn it into the soil when I prepare the land." Coupled with chemical fertilizer, one acre of land with potassium sulfate compound fertilizer 100 catties. Wait until you return to green and then chase the fertilizer again, about 4,000 pounds per acre of land. ”
For some old garlic areas, heavy stubble is serious, fertilizer utilization rate is low, and the fertilization formula of this farmer can be used as a reference. First, the use of organic fertilizers can increase the organic matter in the soil, increase the beneficial microorganisms, and improve the absorption rate of fertilizers. Second, the nitrogen, phosphorus and potassium required for garlic growth can be supplemented with chemical fertilizers.
In addition to the use of compound fertilizer or special fertilizer, it can also be used with fertilizers such as diammonium phosphate, urea, potassium sulfate, etc. to meet the growth needs of garlic. For example, 100 catties of diammonium phosphate per acre, plus 80 catties of urea, and 60 catties of potassium fertilizer. Now there are also some plots of salinization is more serious, the return to the greening period of the application of urea will aggravate the salinization, so the use of slow and controlled release fertilizer in the bottom fertilizer to meet the needs of the entire growth period. In addition to nitrogen, phosphorus and potassium fertilizers, attention should also be paid to the supplementation of trace elements, such as sulfur, zinc and other elements, which can be supplemented by leaf topdressing.
When applying the bottom fertilizer, mix it with half of the amount and make full contact with the soil. The rest is applied at the time of the furrow. When garlic is planted, fertilizer accounts for most of the input cost, so farmers should choose the fertilization formula according to the actual situation when planting, which can save costs while high yield.
