High-yield and stable-yield lodging-resistant peanut cultivation and planting technology

Abstract

The invention provides a high-yield and stable-yield lodging-resistant peanut cultivation and planting technology. The technology comprises the following cultivation steps of seedling at proper time,wherein the whole growth period of peanuts is about 120 days, the air temperature is stabilized at about 12 DEG C in April, and early sowing can be properly conducted; proper planting at a proper place, wherein planting is conducted in dry land of red soil hills and is not suitable for water-deficient high-ridge fields, river tidal land and hilly bottom land clayed soil; reasonable close planting,wherein it is proper that the planting density in the red soil hills is 20000-22000 plants per mu; seed kernel coating, wherein after seeds are mixed with celest, sowing continues; sand compacting for clayed soil improvement, wherein sans compacting is used for improving the soil, and 10-20 cubic meters of sand is used per mu; application of plant hormones for growth adjustment, wherein a 600-fold paclobutrazol solution is sprayed to a land parcel vigorous in growth. Peanuts cultivated and planted through the method have the advantages of being high in yield, stable in yield and resistant tolodging. Meanwhile, compared with the prior art, the yield is increased effectively, and the method is suitable for application and popularization in the society.

Description

technical field [0001] The invention relates to the cultivation and planting of peanuts, in particular to a high-yield, stable-yield and lodging-resistant peanut cultivation and planting technology. Background technique [0002] Peanut is one of the economic crops widely planted in the world, and it is also one of the four major oil crops in my country. my country's peanut planting area is stable at about 45 million mu, accounting for about 18.7% of the world's total planting area, ranking second in the world, and its total output ranks first in the world. At the same time, it is a raw material for the food processing industry and an important export agricultural product. It enjoys a high reputation in the world, and peanut oil, peanut cake, etc. are also widely used in the chemical industry, and occupy an important position in my country's national economy. At present, our country mainly grows oily peanuts and exports peanut oil. In recent years, the peanut food processing ...

AI Technical Summary

Problems solved by technology

So far, my country's peanut research is mostly focused on oily peanuts, and great achievements have been made in the breeding of oily peanut varieties and supporting cultivation techniques. Except for breakthroughs in variety selection and breeding of food peanuts, other aspects of research are relatively relatively low. Its cultivation techniques are basically carried out with reference to oily peanuts. There are many unreasonable places in its planting density, fertilization level, and control methods. In addition, there are many reasons such as extensive planting and low harvest, soil compaction, and serious water and soil erosion. There are many shells, the rate of high-quality fruit is low, and bacterial wilt and leaf spot are serious, and the yield is not high. The average yield per mu is about 200 kg. The economic value is difficult to play, which affects the development of food peanuts and their processing industries. High-yield and stable-yield cultivation techniques are necessary

[0004] Peanut planting in Jiangxi Province is mostly carried out by farmers spontaneously, and the management is relatively extensive. There are many unreasonable places in the planting density, fertilization level, plant regulation, etc., which are only based on experience. The benefits are not fully manifested

The original main peanut varieties in Jiangxi Province are Yueyou 116, Yueyou 551, etc. The varieties planted in the existing technology have low yield, are susceptible to bacterial wilt, have poor lodging resistance, and the field production management is relatively extensive, and farmers plant randomly. Larger, lack of technical regulations for high-yield cultivation, problems in peanut production
