Compound regulator for preventing premature senility and increasing yield of corn and application method thereof

Abstract

The invention discloses a compound regulator for preventing premature senility and increasing yield of corn. Every kilogram of the compound regulator comprises 100-300 mg / kg of butane diacid, 1,000-3,000 mg / kg of chitin, 0.00001-0.00003 mg / kg of forchlorfenuron and 100,000-150,000 mg / kg of potassium dihydrogen phosphate (molecular formula: KH2PO4). The invention further discloses a method for applying the compound regulator. Due to the adoption of the compound regulator, the germination of corn seeds and the growth of seedlings can be promoted, the germination process of seeds is accelerated, the growth and the development of corn leaves and root systems are promoted, the leaf area and the root quantity of corn are increased, the chlorophyll content of leaves and the root system activity of corn are increased particularly at the middle and later periods of grain filling, the activities of anti-oxidases such as SOD (Superoxide Dismutase) and CAT (Catalase) and the like in the corn leaves and root systems are increased remarkably, the accumulation of active oxygen in the leaves and root systems is reduced, the peroxidation action of the membrane lipid is restrained, premature senility is prevented, and the yield of corn kernels is increased.

Description

technical field [0001] The invention relates to the technical field of crop regulators, in particular to a compound regulator for preventing premature senility and increasing yield of corn and a use method thereof. Background technique [0002] Corn is an important food and fodder crop in my country, and occupies an extremely important position in the national economy. The abundance or decline of corn production has gradually become an important factor affecting the balance of food supply and demand in my country and determining the development of animal husbandry. But in the limited area of ​​arable land, the area of ​​corn planting is limited to a certain extent, how to increase the yield per unit area becomes the key to the future corn production. Leaf is an important organ for plants to carry out photosynthesis and produce organic matter. About 95% of the dry matter of corn comes from photosynthetic accumulation. Research results have shown that if the life of functional...

Problems solved by technology

The first is the soil condition, the quality of the plowed land is poor, the soil permeability is poor, and the small amount of farmyard manure is applied, which leads to the lack of organic matter in the soil, the imbalance of carbon and nitrogen ratio, and the reduction of biological nitrogen fixation ability, resulting in insufficient nutrition in the later stage of corn growth.

The second is the cultivation conditions. The unreasonable planting density or planting form of corn will relatively reduce the nutrient area of ​​a single plant; continuous cropping for many years will cause a large amount of Fusarium, Pythium and take-all pathogens to accumulate in the soil, affecting the growth of corn
