Functional formula fertilizer special for period of seedling establishment of wheat

Abstract

The invention discloses functional formula fertilizer special for the period of seedling establishment of wheat. The functional formula fertilizer includes basic nutrient fertilizer of nitrogen, phosphorus and potassium, and is characterized in that the basic nutrient fertilizer includes brassinolide, zinc sugar alcohol, disodium octoborate tetrahydrate, a novel higher aliphatic acid film, cetearyl glucoside and evening primrose seed oil. According to the functional formula fertilizer special for the period of seedling establishment of the wheat, the nutrition is balanced, the use amount is low, the nutrient requirements of the period of seedling establishment of the wheat are completely met, rooting, leafing and tillering are promoted, wheat stalks are thick and strong, stress resistanceis high, the wheat yield, the quality and the protein content are improved, the safety and non-toxicity are achieved, resistance to diseases and pests is enhanced, the pesticide use amount is decreased, pesticide residue on the wheat can be avoided, the soil structure is advantageously improved, the wheat protein content is increased, the wheat fragrance is increased, and the processability is enhanced.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special functional formula fertilizer for wheat rejuvenation period. Background technique [0002] As one of the staple foods, wheat occupies a very important position in people's daily dietary nutrition. At present, in order to obtain high quality and high yield of wheat, rational fertilization is still one of the key technical measures. Studies have shown that most of the nutrients absorbed by wheat come from fertilizers applied in the current season. Scientific and reasonable fertilization during each growth period of wheat is obviously necessary for increasing wheat production and income. [0003] The turning green period of winter wheat means that after the average daily temperature rises steadily above 0°C, the wheat slowly resumes growth. After 50% of the plant year, the newly grown leaves protrude from the sheath by 1 to 2 cm, and the field turns from ...

Problems solved by technology

[0006] However, since commonly used nitrogen fertilizers (such as urea, ammonium bicarbonate, ammonium sulfate, etc., and slow-acting nitrogen fertilizers such as long-acting urea are difficult to promote because of their high cost) are instant fertilizers, they will quickly dissolve, decompose or be destroyed after being applied to the soil. Biological fixation accelerates the conversion of available nitrogen, but cannot synchronize the release rate of available nitrogen with the progress of nitrogen absorption by winter wheat

However, one-time basal application of a large amount of quick-acting nitrogen fertilizer not only tends to cause excessive vegetative growth of winter wheat at the seedling stage, and even burns the seedlings, but also (due to exceeding the nutrient carrying capacity of the soil) can easily lead to agricultural non-point source pollution and groundwater pollution.

[0007] At present, there are no special functional formula fertilizers and cultivation and fertilization methods suitable for the growth and development characteristics and nutrient requirements of wheat during the greening period.
