[0004] In order to increase crop yield, Chinese patent CN 10754893A discloses a method for intercropping corn and water spinach. Although the yield of intercropping corn is improved, the effect is not significant, and the effect on the quality of corn is unknown. There is yield, but no growth has been achieved; this is consistent with Wang Xiaoli et al. Research on the reduction of nitrate content in soil and vegetables by intercropping of corn / water spinach [J]. Journal of Environmental Science, 2003(04): 463-467. The research conclusion is consistent, Under the condition of intercropping, the yield and quality of corn and water spinach are not improved at the same time, which cannot meet the market demand

Embodiment 1

[0026] (1) Site selection: select fertile, deep soil, and well-drained plots with a slope of 7°;

[0027] (2) Base fertilizer application: shallow plowing before sowing, remove stubble, and apply 1800kg of slow-release long-acting mixed fertilizer to each hectare of land; the slow-release long-acting mixed fertilizer is 50:15:8:16:11 Manure: urea: phosphorus pentoxide: potassium chloride: ammonium sulfate; wherein human and animal manure is fermented and decomposed by fermentation bacteria, adding viride trichoderma bacteria in the fermentation process for sterilization;

[0028] (3) intercropping: each row of corn is intercropped with one row of water spinach; the plant spacing of corn is 30cm, the row spacing is 35cm; the plant spacing of water spinach is 15cm, and the row spacing is 40cm; before sowing, the seeds of water spinach are soaked for 10 hours through compound fertilizer; The fertilizer is an amino acid and acetylcholine composition with a mass ratio=0.7:1; the am...

Abstract

The invention belongs to the technical field of agricultural planting, and in particular relates to a cultivation method for improving the quality and yield of intercropping corn. The method provided by the invention can increase the yield and improve the quality of water spinach and corn. Compared with single-crop corn, the aboveground biomass of corn in the present invention can be increased by 52.68-67.79% per square meter; the corn grain yield can be increased by 40.54-52.02% per square meter The corn lysine content can be increased by 73.69-84.21%; wherein compared with the single water spinach, the output of the water spinach in the present invention can be increased by 39.12-42.93%; the content of reducing vitamin C in the water spinach can be increased by 34.02-36.64% The present invention reduces the nitrate content in water spinach by 1049.35-1058.72mg / kg; greatly reduces the nitrate content in vegetables, reaching the standard for raw food; reduces the carcinogenic risk of nitrous acid to human body.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a cultivation method for improving the quality and yield of intercropping corn. Background technique [0002] my country is a country with a large population and has a large demand for food and vegetables, but the supply is obviously insufficient recently. The stable supply of food and vegetables is not only able to meet people's living needs, but also an important factor in maintaining my country's economic stability. Corn is one of the most important grains in the world. Among them, corn accounts for 50% of the food composition of Asians, and more than 90%. It is an important part of people's life; Vegetables with cellulose, its edible fiber is composed of cellulose, hemicellulose, lignin, mucilage and pectin, which has the effect of laxative and detoxification, and is also a common vegetable on the table of our people. [0003] Intercropping refers t...
