Different fertilizer combinations on water supply and demand of winter wheat
Better match water level,[link widoczny dla zalogowanych], in particular, was applied to phosphate fertilizer and improve soil water saving of space. Studies have shown that ecological conditions in the area of farmland under the greatest water use efficiency of winter wheat yield model is the highest combination of nitrogen and phosphorus fertilizer organic manure units. But in the case of organic fertilizer nitrogen application should be appropriate to reduce the amount of In short, rational fertilization can not only maintain the soil nutrient balance,[link widoczny dla zalogowanych], in proportion to crop nutrition,[link widoczny dla zalogowanych], water and fertilizer can increase yield of full play; and soil moisture can increase the input,[link widoczny dla zalogowanych], so that winter wheat ecosystem suitability of soil moisture are more substantial increase. Each growth stage of winter wheat to reduce the water supply level of dislocation and stress, to increase food production purposes. Different fertilizer combinations. The crop and production end units into consideration the growth and development stages for the different level of water deficit allowed to tie down the value needs further study.
