A cultivation method suitable for autumn sowing and spring transplanting of quinoa in coastal saline-alkali land

Abstract

The invention discloses a cultivation method suitable for autumn sowing and spring transplanting of quinoa in coastal saline-alkali land, comprising seven steps: (1) growing seedlings in the open field in autumn; (2) management of seedbeds in spring; (3) field preparation and fertilization; (4) quinoa Transplanting wheat seedlings; (5) manual intertillage and weeding; (6) water and fertilizer management; (7) timely harvesting. The present invention adopts autumn sowing, and its sowing amount is only half of that of conventional spring sowing, and does not need to be covered with plastic film, which effectively reduces the planting cost; the farming operation is simple and feasible, and the thinning link is removed, saving time and effort; the seedlings emerge neatly and can be transplanted in spring The survival rate reached 100%, which laid a good foundation for a large-scale balanced production increase; the method of autumn sowing and spring shifting was adopted to advance the growth period of quinoa by 30 days. It is beneficial to realize the reasonable collocation of early, middle and late-maturing varieties; the cultivation methods are matched in order to realize the high yield, high quality and grain return of quinoa.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method suitable for autumn sowing and spring transplanting of quinoa in coastal saline-alkali land. Background technique [0002] Quinoa( Chenopodium quiona Willd) is native to the Andes region of South America. It is an annual, dicotyledon Chenopodiaceae crop. It is the main food crop of local residents. It has very high nutritional value and is rich in protein, lysine, cellulose and a variety of Trace elements are the only whole protein grains in the plant kingdom, known as "super grains" and "Inca gold". Quinoa is easy to cook, has a unique taste and fragrance, and is easy to digest. It has the characteristics of low calorie, low sugar, and zero cholesterol. On the one hand, it can supplement the nutrients needed by the human body and enhance the body's functions; And endocrine system, play the role of disease prevention. [0003] Quinoa has the chara...

Problems solved by technology

At present, the sowing period of coastal saline-alkali land is generally from mid-May to the end of the month, and the sowing amount is large; although the film is covered after sowing, the emergence of seedlings is still uneven, the emergence rate and survival rate are low, and the phenomenon of lack of seedlings and broken ridges is obvious, and seedlings must be thinned after emergence. And supplement seedlings, the planting process is cumbersome and the cost is high

Due to the spring sowing of quinoa, the growth period is limited, the variety selection range is small, and it is difficult to mature normally
