Three attentions should be paid to the application of wax fertilizer in growing wheat
In wheat fields with weak seedlings sowing late, poor soil fertility and insufficient base fertilizer, wax fertilizer should be fully applied, mainly quick-acting fertilizer, about 40 piculs of rotten pig and cow manure per mu, or 20 kilograms of ammonium bicarbonate, or about 10 kilograms of urea should be applied when it rains and snows, in order to promote stem growth and tiller increase. In general, the wheat fields deficient in phosphorus and potassium showed yellowing in the lower part of the leaves, redness of the leaf tips and chlorosis of the old leaves, followed by necrosis and thin stems. Phosphate and potash should be applied, and 25 kg of superphosphate, 5-6 kg of potash, or 100-150 kg of plant ash should be applied per mu. Plant ash can play the role of heat absorption, heat preservation and antifreeze.
In wheat fields with abundant base fertilizer, soil fertility fertilizer, early sowing and prosperous growth, the amount of wax fertilizer should be controlled, less or no chemical fertilizer should be applied, mainly soil and miscellaneous fertilizers such as pond mud, and measures should be taken to control prosperity and promote strength in combination with suppression. improve the winter environment of wheat. For the pseudo-prosperous seedlings with few tillers and slender leaves, the seedlings should be thinned in time to prevent the population from being too large, and deep ploughing can be carried out at the same time.
The strong seedlings have green leaves and yellow heart leaves. From a distance, the strong seedlings with glossy wheat seedlings, early sowing, sufficient bottom fertilizer and sufficient soil moisture can be properly applied, mainly soil and miscellaneous fertilizer, and combined with suppression, about 25 piculs of human and animal feces and urine per mu are applied to supplement the nutrients needed for the growth of wheat seedlings.

Skillful in planting late sowing wheat with high yield
Compared with suitable sowing wheat, late sowing wheat consumes relatively less fertilizer, but because late sowing wheat generally consumes more nutrients in the previous crop and reduces available nutrients in the soil, coupled with late sowing, the early seedlings are small and weak, so it is not suitable for water and fertilizer management.

How to prevent Winter Seedling death from growing Wheat
In recent years, wheat freezing injury has occurred every year in our county. In addition to the factors of wheat varieties themselves, the management measures in winter are mainly ignored by farmers. In order to reduce the occurrence of wheat freezing injury this year, the technical instructor specially proposed the following techniques for the project village.
