Chenopodium quinoa cultivation method in low-altitude plain area

Abstract

The invention provides a chenopodium quinoa cultivation method in a low-altitude plain area. The method comprises the following steps: before sowing, applying 5-10 kilograms of any one of urea, ammonium hydrogen phosphate and ammonium sulfate, 3-8 kilograms of any one of potassium chloride and potassium sulfate or 1-3 tons of organic fertilizer as a base fertilizer per mu, ploughing with the depth of 10-20 centimeters, sowing by adopting an all-land film mulching hole sowing method, keeping the hole spacing of 10-50 centimeters, the line spacing of 30-100 centimeters and 1-4 seedlings in each hole, and coating seeds before sowing; performing seedling uniformizing in an eight-leaf stage, performing first weeding, and performing second weeding in a squaring stage; in the squaring stage, spraying leaf surfaces with any one of chlorobromoisocyanuric acid with the mass concentration of 0.1%-0.5%, monopotassium phosphate with the mass concentration of 0.1%-0.2%, 1000-5000 ppm of brassinolide and diethyl aminoethyl hexanoate twice at the interval of 10 days; ensuring that irrigation is not needed in the whole growth period, and carrying out harvesting when the plants are yellow and ripe and grains are hardened and exposed. According to the method, the seedling rate can be effectively increased, the seed consumption is reduced, the chenopodium quinoa production cost is reduced, the field lodging rate is reduced, and the disease and pest control difficulty is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for cultivating quinoa in low-altitude plain areas. Background technique [0002] Quinoa (Chenopodimu quinoa willd, 2n=4x=36) is an annual dicotyledonous plant belonging to the family Amaranthaceae (Chenopodiaceae) and the genus Chenopodium. It is native to the Andes in South America. Quinoa is rich in protein, starch, fat, minerals, vitamins and other nutrients. Its grain protein content is about 7-23%, rich in eight kinds of amino acids necessary for human body, and is an excellent protein source for human beings. The fat content of quinoa seeds is about 6%, of which oleic acid accounts for about 25%, and linoleic acid accounts for about 50%, which is a healthy oil. The starch content of quinoa is about 60%, mainly composed of D-xylose and maltose, and the content of glucose and fructose is very low. It is an ideal food for diabetics. At the same ti...

Problems solved by technology

Problems in this trial planting method: 1. The Chengdu Plain is rainy and hot at the same time. In this method, the quinoa growth period and the mature period encounter more rainy summers, and there are many diseases in the quinoa emergence and growth periods, and the management is difficult. The yield of quinoa is relatively low. Low, the yield per mu is generally below 50 kg
