Salt-resistance formulation for improving salt resistance of wheat and method of use thereof

Abstract

A salt-resistant preparation for improving the salt resistance of the wheat and an application method thereof belong to the technical field of improving the salt resistance of the wheat to increase the wheat production. The method comprises the following steps: 1) soaking the salt resistance preparation, wherein, with the overall weight being 1kg , the final composite ingredients are 3-4g of Ca (NO3)2, 1.2-1.5g of KH2PO4, 1.5-2g of KI, 0.35g of MnSO4, 10mg of Na2SeO3, 40-60mg of cytokinin, and the balance water; 2) spraying the salt resistant preparation on the surfaces of leaves, wherein, with the overall weight being 1kg, the final composite ingredients are 1-1.2g of Ca (NO3)2, 0.25-0.3g of KH2PO4, 0.35g of KI, 0.1g of MnSO4, 2mg of Na2SeO3, 2-10mg of cytokinin, and the balance water. Wheat seeds are soaked in the salt resistant preparation once before being planted, and the salt resistant preparation is sprayed on the surfaces of the leaves after fifteen days from the wheat seedlings turn green in the spring of the next year. The invention has the advantages of significantly improving the ratio of emergence of wheat seeds under high salinity stress, promoting the growth of wheat plants, increasing the production of the wheat by 15-20 percent, and being suitable for the soil with salt contents being 0.3 percent.

Description

technical field [0001] The invention relates to the technical field of improving the salt resistance of wheat to increase the yield of wheat, in particular to a salt-resistant preparation for improving the salt-resistance of wheat and an application method of the salt-resistant preparation. technical background [0002] The full use of salinized soil is an important way to promote the development of agricultural economy and improve the agricultural ecological environment. my country has more than 40 million hectares of salinized and secondary salinized land, accounting for about 1 / 10 of my country's cultivated land. Large areas of salinized land have seriously affected grain production and have become a limiting factor that cannot be ignored in my country's agricultural production. With the increase of population and the decrease of arable land, my country's total grain output will only reach 640-700 million tons by 2030, that is, the grain output must be increased by more ...

Problems solved by technology

Through reasonable water and soil management and chemical improvement measures, plant salt damage can be partially alleviated, but the cost is too high; although breeders have achieved certain results by cultivating and screening salt-tolerant crop varieties, as disclosed in Chinese patent CN1230593 using a A new means of introducing exogenous DNA to improve the salt resistance of recipient plants, but it is still not ideal from the current situation
