Crop yield-increasing agent and preparation method thereof

Abstract

The invention provides a crop yield-increasing agent and a preparation method thereof; the crop yield-increasing agent is prepared from, by weight, 20-40 parts of gibberellin, 20-30 parts of compound sodium nitrophenolate, 20-30 parts of 5-aminolevulinic acid, 10-25 parts of plant active liquid, 45-75 parts of a filling material, 20-40 parts of solubilizer, 10-15 parts of salicylic acid, and 50-85 parts of water. The crop yield-increasing agent is nontoxic to human and livestock, easily degrades in the environment and is free of residue; compared with other phytohormone yield-increasing agents, the crop yield-increasing agent has more stable effect and longer acting time and can provide significantly increased fruiting rate and yield of rice.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a crop yield increasing agent and a preparation method thereof. Background technique [0002] Rice is an important food crop in many countries, including my country, providing food and nutrition for more than 50% of the world's population. Under the new situation where the amount of arable land is decreasing, disasters are frequent, and the demand for food is increasing rigidly, the stable development of rice production must fully rely on science and technology to tap the potential of increasing rice production. Breeders have further increased yields and broken yield bottlenecks by breeding new high-yielding varieties such as super rice. However, super rice varieties are often accompanied by the disadvantages of poor stress resistance and unstable yield, and it is difficult to realize their yield potential in field production. [0003] In recent years, extreme cli...

Problems solved by technology

As a result, soil fertility and nutrients are lacking and unbalanced, and rice production is reduced.

However, most farmers simply attributed it to the lack of soil fertilizer, and then applied a large amount of common chemical fertilizers such as nitrogen, phosphorus, and potassium. As a result, the middle, trace elements, and beneficial elements required by rice in the paddy field were extremely deficient, destroying the soil aggregate structure and limiting As rice grows and develops, the soil gradually changes from a bacterial type to a fungal type, and the soil environment gradually deteriorates. Moreover, due to repeated cropping, soil diseases and insect pests, especially rhizosphere nematodes, and other diseases and insect pests have become more and more frequent, and the beneficial bacteria in the soil have become less and weaker. , aggravated the increase of root system secretion of toxins and the accumulation of root self-toxicity, etc., which comprehensively affected the healthy growth of rice, resulting in reduced yield and poor quality of rice.
