Problems solved by technology

[0004] Moreover, most vegetables are shallow root crops, and compared with field crops, they are highly dependent on water and fertilizer, so irrigation and fertilization play a very important role in ensuring the growth of vegetables, but frequent irrigation and excessive fertilization in production are not only Reduce the utilization rate of water and fertilizer, and cause the quality of vegetables to decline, and the nitrate content in groundwater to exceed the standard

Embodiment 1

[0021] A method for intercropping corn and water spinach, comprising the following steps:

[0022] Step (1) Land selection and land preparation: Select fertile, deep soil, loose, and well-drained plots. After the harvest of the previous crop, remove the root stubble, deeply plow and sun-dry, receive precipitation, and shallow plow and harrow before sowing to make the soil finely divided and the soil Soft, flat ground, solid plowing layer;

[0023] Step (2) Apply enough base fertilizer: combined with plowing and land preparation, apply fully decomposed farmyard manure 6300kg, urea 350kg, compound fertilizer 1200kg, nitrogen fertilizer 300kg, P 2 o 5 150 kg, and the soil is harrowed and leveled;

[0024] Step (3) Intercropping: Water spinach is planted by sowing or drilling. After sowing, cover it with fine soil to a thickness of 1 cm; when sowing, first draw a 2-3 cm deep ditch with a distance of 15 cm, and then spread the seeds evenly in the ditch. Inside, cover with fine s...

Abstract

The invention discloses an intercropping method of corn and water spinach, comprising the following steps: (1) selecting and preparing the land; (2) applying 6300 kg of fully decomposed farmyard manure, 350 kg of urea, 1200 kg of compound fertilizer and 300 kg of nitrogen fertilizer per mu in combination with ploughing and soil preparation. kg, P2O5150 kg; (3) The water spinach is planted by broadcasting or drilling; the bred corn seedlings are transplanted on both sides of the water spinach; (4) The water spinach is sprayed with 10-15% dilute human excrement and urine at the seedling stage. When the seedlings have 3 to 4 true leaves, 15 to 20 kg of compound fertilizer and 2 to 4 kg of urea are used in combination. During the harvesting period, 5 to 8 kg of compound fertilizer per acre is used for top dressing, and watered 1 to 2 times a day. ; Apply compound fertilizer twice during the growth of corn, and apply compound fertilizer 20-40kg / mu each time. The method for intercropping corn and water spinach provided by the invention, on the basis of increasing the yield of water spinach, interplants corn, saves resources, increases the income of growers, and can reduce the accumulation of nitrates in vegetables and reduce the carcinogenic threat of nitrosamines to the human body.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to an intercropping method of corn and water spinach. Background technique [0002] Water spinach is an alkaline food and contains potassium, chlorine and other elements that regulate the balance of water and liquid. After eating, it can reduce the acidity of the intestinal tract, prevent intestinal flora imbalance, and is beneficial to cancer prevention. This is also a life tip. The niacin and vitamin C contained in it can lower cholesterol and triglycerides, and have the effect of lowering fat and losing weight. The chlorophyll in water spinach is known as the "green elf", which can clean teeth, prevent caries, eliminate bad breath, and build skin. It can be called a beauty product. It is rich in crude cellulose, which is composed of cellulose, hemicellulose, lignin, mucilage and pectin, etc. It has the functions of promoting intestinal peristalsis, laxa...
