Method for planting fruit of thorny elaeagnus in saline-alkali land

Abstract

The invention relates to a method for planting fruit of thorny elaeagnus in saline-alkali land. The method includes the following steps: preparing a bio-organic fertilizer, wherein the bio-organic fertilizer consists of straw fermentation products, livestock manure, peat, rice bran and potassium humate; selecting and preparing the land; selecting and planting seedlings; and preforming fertilizer and water management and cultivation management. The method has simple operation, can plant the fruit of thorny elaeagnus in moderate saline-alkali soil without later curing, has fast growth speed, short seedling slowing period and high survival rate of the seedlings, and can fully and effectively utilize the existing large-area coastal mudflat in China, so that economic benefits are improved and the application prospect is good.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for planting Ebi sativa in saline-alkali land. Background technique [0002] Soil salinization is a worldwide problem. According to statistics, the area of ​​coastal tidal flats in my country is about 6 million hm 3 , while the total area of ​​coastal tidal flats in Jiangsu is about 100 hm 3 , accounting for 1 / 6 of the tidal flat area in China. The physical and chemical properties of saline-alkali soil are poor, the soil is barren, the organic matter and nutrient content are generally low, the ability to retain fertilizer and water is poor, and the salt content is high. These are the common characteristics of difficult sites in coastal tidal flat areas. These environmental conditions will directly damage the cells, tissues and organs of cultivated plants, resulting in shortened plant life cycle and even death. Therefore, the difficult site co...

The method of carrying out original soil greening in coastal tidal flat saline-alkali land generally includes the following steps: first try salt absorbing agent to improve coastal tidal flat saline-alkali land, and then plant original soil greening plants on the improved tidal flat saline-alkali land. In the original soil greening process, there are the following Disadvantages: It cannot effectively reduce the salt content in the tidal flat saline-alkali soil; the soil's fertilizer retention capacity is poor, and it is easy to lose after fertilizer application; the soil's water retention capacity is poor, and the water is easy to lose, and the moisture content in the soil is low; Effectively reduce the pH value of the soil; the survival rate of native plants is low and the growth is slow

[0005] The applicant tried to directly transplant the obtained cutting seedlings of Ebi sativa to the tidal flats with high saline-alkali content, but the survival rate was very low, and the purpose of landscaping and improving soil fertility on coastal tidal flats could not be realized. Tissue culture propagation method obtains the method for the seedlings of S. esculenta. However, the prior art has not yet reported that S. esculenta is used for coastal tidal greening and soil improvement.
