Problems solved by technology

[0007] However, the coastal saline-alkali soil has high salt content and poor soil structure, and there are common problems of difficult seedling emergence and lack of seedlings.
In addition, due to the special climatic conditions of coastal saline-alkali land, during the actual cultivation process of quinoa, quinoa will often be aborted due to temperature and humidity conditions. main obstacle
The above-mentioned technologies cannot solve the technical problems of growing quinoa in coastal saline-alkali

Abstract

The invention relates to a method for quinoa seedling raising, transplanting and planting suitable for seashore saline-alkali soil. The method comprises the following steps that (1) quinoa seeds are obtained and sown into a seedling raising matrix to prepare transplanted seedlings; (2) the transplanted seedlings and the seedling raising matrix are transplanted into furrows with the depth of 18-22cm, and seedlings are arranged and thoroughly watered; (3) normal field management is carried out. According to the method, the specific seedling raising matrix is used for cultivating the strong seedlings the first time, the growth period of quinoa is earlier, quinoa pollination and normal development of grains are ensured, and the problem of incapability of popularizing quinoa planting in the coastal saline-alkali soil at present is solved.

Description

technical field [0001] The invention relates to a quinoa seedling-raising, transplanting and planting method suitable for coastal saline-alkali land, and belongs to the technical field of saline-alkali land cultivation. Background technique [0002] Soil salinization is a global ecological problem. According to incomplete statistics from UNESCO and FAO, the global saline-alkali land area has reached 9.55×10 8 , my country's saline-alkali land area is 99.13 million hectares, and saline-alkali land is widely distributed in my country. Northwest, North China, northeast and coastal areas are the main distribution areas of saline-alkali soil in my country, and coastal saline-alkali land occupies a high proportion of saline-alkali soil area in China. The coastal saline-alkali land of the Yellow River Delta is an important reserve land resource in my country. At present, the crop planting mode in the saline-alkali land of the Yellow River Delta is single, the yield is low, and the...
