Enzyme-enzyme composting and controlling compost of corn “Bal tip”

The lack of firmness at the top of a corn ear is known as baldness or baldness, and this symptom reduces the number of corn kernels and causes a reduction in yield.

cause

Maize floret differentiation, silking, and grain formation begin in the middle and lower parts of the ear, and thereafter proceed upward or downward simultaneously from this point, and end at the top. In case of unfavorable environmental conditions, the top florets or fertilized embryos are often aborted due to insufficient supply of nutrients.

There are three common causes of baldness: First, the top florets are degraded into sterile flowers due to drought or fertilizer shortage during differentiation. The second is that before tasselling encounters hot and dry weather, heading loose powder is taken out in advance or the top of the filaments is drawn out too late, and the timing of fertilization is lost, resulting in baldness. Thirdly, the planting is too dense, the supply of fertilizer is in short supply, or drought, or suffers from floods, or even in rainy weather, the photosynthesis of the leaves is weakened, and the fertilized embryos at the top of the ear cannot get enough nutrients and cannot develop into grains.

Control methods

According to the cultivation of corn plots, select suitable varieties. Hard-bite breeds appear to be lighter, while dents are heavier.

Promote the use of fermented enzyme composted compost, such as organically active manure fertilizer, applied 250 kg per acre.

The use of formula fertilization technology to strengthen field management before and after flowering, adequate fertilizer and water conditions to ensure the supply of nutrients when female flower differentiation. If necessary, spray active liquid fertilizer or high-efficiency amino acid liquid fertilizer.

Artificially assisted pollination was applied to the late varieties or plants.
