Problems solved by technology

[0003] Due to its high salt content, low nutrient content, and poor soil structure, saline soil will seriously reduce the yield of common crops or even fail them. Therefore, common crops cannot be directly planted on salinized farmland

Embodiment 1

[0030] Embodiment 1, a kind of method of planting New Zealand spinach in high salinity soil

[0031] The test site is as follows: Seawater intrusion land in Tanlan Village, Puqian Town, Wenchang City, Hainan Province.

[0032] The soil conditions and other conditions of the test site are as follows: the soil is sandy soil, and the average salt content of the farmland after seawater irrigation is about 2%. The conditions of light, water, humidity and heat are superior, there is no frost throughout the year, and the four seasons are distinct. The annual average temperature is 23.9°C, the annual average accumulated temperature >10°C is 8474.3°C, and the annual average sunshine is 1953.8 hours.

[0033] The test method is as follows:

[0034] 1. New Zealand spinach seed germination

[0035] Because New Zealand spinach seeds have thick skins and are not easy to germinate, 1 kg of New Zealand spinach seeds (from the University of Arizona in the United States) was soaked in 10 kg ...

Abstract

The invention discloses a method for growing New Zealand spinach in saline-alkali land. In the present invention, the New Zealand spinach seeds are first germinated and seedling-raised, and then transplanted into salinized farmland with a salt content of 0.6-2.5%. They can be picked and eaten after about one month of growth. Continuously harvested, the cumulative yield per mu of New Zealand spinach grown in salinized farmland can reach more than 10,000 kilograms. The present invention is the first to successfully plant New Zealand spinach in a large area on the salinized farmland, realize the growth and reproduction of New Zealand spinach in the saline soil environment, and has the characteristics of one-time planting, multiple picking, long production period and high yield; New Zealand spinach grown in saline soil has a slightly higher salt content, correspondingly less pests and diseases, and does not require the application of pesticides. It has the potential to be developed into green and pollution-free vegetables, and the economic benefits are particularly significant. The method of the invention is an effective method for developing saltland agriculture and enlarging agricultural production, and has great potential for development.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for growing New Zealand spinach in saline-alkali land. Background technique [0002] The harm of soil salinization to agriculture is a global problem, and salt stress has become one of the important abiotic stresses. According to incomplete statistics from UNESCO and FAO, there are about 1 billion hectares of various saline soils in the world, accounting for 10% of the global land area, of which 1 / 2 of the irrigated land is affected by salinization, and every year About 10 million hectares of land are abandoned due to secondary salinization of soil. There are also a large number of saline-alkali lands in China. According to incomplete statistical analysis, the total amount of various types of saline soil in my country is 1.487 billion mu, especially the coastal zone and tidal flats reach more than 200 million mu, and there is a growing trend every year. . How...
