Abstract

The invention discloses a green planting method for sweet corn. The method comprises the steps of subsoiling and land preparation are carried out before planting, an organic fertilizer is prepared andapplied as a base fertilizer, wherein the organic fertilizer is at least one of fruit and vegetable straw residue organic compost or bio-organic fertilizer with an application amount of 500-1000 kg / mu, and an organic water soluble fertilizer with an application amount of 20-50 kg / mu is auxiliarily applied; seeding is carried out, wherein double-row planting is adopted, and the row spacing is 0.8m*0.2m; after seedling emergence of the sweet corn, 20-30 kilograms of an inorganic fertilizer is top-dressed on 3000-3500 plants per mu, and topdressing is completed in 4-5 times; after harvesting, the corn straw is decomposed and returned to the field in situ. According to the method, only biological pesticides are adopted and no chemical pesticide is adopted in the whole process, fertilization mainly adopts the organic fertilizer, the method follows the ecosystem nutrient cycle rule, the input of external chemical fertilizers is reduced, not only is the effect ensured that the yield of the sweet corn is not greatly reduced, but also the quality of the sweet corn is improved.

Description

technical field [0001] The invention belongs to the field of fruit corn planting and relates to a green planting method of fruit corn. Background technique [0002] With the development of my country's social economy, the production management level of modern agriculture has gradually improved, and people's requirements for the quality of agricultural products have also increased significantly. Fruit corn is a variety of fresh corn, which can meet the needs of people to eat directly like picking fruits. Due to the high input of chemical fertilizers and pesticides in traditional planting methods, the quality of fruit and corn has declined and the risk of pesticide residues has increased, which has also led to high market risks and prominent food safety issues. In addition, due to the high economic value of fruit corn and its short growth cycle, the multiple cropping index in only one year is high. Therefore, long-term continuous cropping will lead to acidification and degrad...
