Slow release fertilizer capable of improving soil and resisting dry and hot wind and used for wheat

Abstract

The invention discloses slow release fertilizer capable of improving soil and resisting dry and hot wind and used for wheat. The slow release fertilizer is prepared from raw materials in parts by weight as follows: 25-45 parts of kelp residues, 10-18 parts of silkworm droppings, 15-25 parts of cottonseed meal, 4-10 parts of monopotassium phosphate, 6-12 parts of calcium magnesium phosphate, 10-20 parts of ammonium nitrate, 6-14 parts of monopotassium phosphate, 4-8 parts of calcium superphosphate, 30-40 parts of urea, 0.006-0.012 parts of fermented compound bacteria, 4-10 parts of modified whey powder, 3-7 parts of choline chloride, 4-8 parts of abscisic acid, 3-7 parts of glycosaminoglycan, 0.4-1 part of ammonium phosphate, 0.4-1 part of manganese ammonium phosphate, 1.5-2.5 parts of quick-acting boron, 1.5-2.5 parts of sodium chloride and 0.4-1 part of slag. The slow release fertilizer is low in cost, and can effectively prevent and relieve damage of dry and hot wind to the wheat and improve stress resistance of the wheat. The slow release fertilizer has a good film-forming property and can reduce water evaporation and effectively improve the soil structure.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release fertilizer capable of improving soil and wheat resistance to dry and hot wind. Background technique [0002] Generally speaking, when the temperature is higher than 32°C, the relative humidity is lower than 30%, and the wind speed is greater than 2m / s, "dry hot wind" will appear. The formation of hot and dry wind causes the temperature in the field to rise sharply and the humidity to drop sharply. Coupled with the influence of wind force, the water potential difference between the inside and outside of the leaves of wheat plants expands rapidly, causing water imbalance in the plants. Wheat plants lose a lot of water and the water content of leaves drops rapidly. , Chlorophyll is disintegrated and destroyed, and the synthesis of chlorophyll is blocked, which destroys the normal progress of plant photosynthesis, and the photosynthetic rate drops significantly.

Problems solved by technology

The formation of hot and dry wind causes the temperature in the field to rise sharply and the humidity to drop sharply. Coupled with the influence of wind force, the water potential difference between the inside and outside of the leaves of wheat plants expands rapidly, causing water imbalance in the plants. Wheat plants lose a lot of water and the water content of leaves drops rapidly. , Chlorophyll is disintegrated and destroyed, and the synthesis of chlorophyll is hindered, which destroys the normal progress of plant photosynthesis, and the photosynthetic rate drops significantly

Water and nutrients cannot be supplied in time, and the function of wheat root system to absorb water and mineral elements is reduced, and the vitality is weakened
