Example Embodiment

[0031] Example 1 A method of interplanting potato and vegetable in saline-alkali soil

[0032] 1. Types of saline soil

[0033] It is a medium-to-severe carbonate-type saline-alkali land. The soluble salt composition of 100 grams of soil contains soda content of 0.55-0.62 milliequivalents, soil pH is 8.8, soil salt content is 1.4-1.5%, and total soil porosity is 18% , Soil bulk density is 1.5g / cm 3 , The total number of microorganisms in the soil is 20×10 4 / g dry soil, the content of alkali hydrolyzable nitrogen in the soil is 8mg / kg.

[0034] 2. Preparation of base fertilizer

[0035] The mass ratio of the raw material components of the base fertilizer is:

[0036] 30 parts of straw rot, 35 parts of maleic anhydride, 12 parts of citric acid, 13 parts of phosphorus nitrate, 12 parts of biochemical fulvic acid, 10 parts of humic acid, 2 parts of chelated iron, 1 part of chelated zinc, 14 parts of ammonium sulfate , 14 parts of urea phosphate, 5 parts of urease inhibitor, 3 parts o...

Example Embodiment

[0069] Comparative Example 1:

[0070] Using the planting method described in Example 1, only the steps of "four. planting vegeta and potatoes" were changed. The changes were: only vegeta was planted. The planting density of vegeta was 25cm in rows, 15cm in holes, and 2 per hole. -3 strains.

Example Embodiment

[0071] Comparative Example 2:

[0072] Using the planting method described in Example 1, only the steps of "four. planting vegetables and potatoes" were changed, and the changes were: only potatoes were planted, and the planting density of potatoes was as follows: potatoes were grown in normal ridges, the row spacing was 40 cm, and the ridge width 25cm, the ridge height is 15cm, and one row of potatoes is planted on the ridge, and the distance between the potato plants is 20cm.

Abstract

The invention provides a sedum aizoon and potato interplanting method used in saline alkali soil. The sedum aizoon and potato interplanting method includes the steps of potato planting, sedum aizoon seedling culturing and sedum aizoon and potato interplanting, wherein wide-line ridge culturing is adopted for potatoes, the line spacing is 85 cm, and the row spacing is 20 cm; two rows of sedum aizoon are planted between the two ridges of the potatoes, the line spacing of the sedum aizoon is 25 cm, the hill spacing is 15 cm, 2 to 3 strains of sedum aizoon are planted in each hill, and the distance between the potatoes and the sedum aizoon is 30 cm. The sedum aizoon and potato interplanting method has the advantages that the survival rate of the sedum aizoon is 99.5%, the annual output of the sedum aizoon reaches 7500 kilograms per mu, the survival rate of the potatoes is 91.7%, and the annual output of the potatoes is 2360 kilograms per mu; the soil is improved effectively, after the sedum aizoon is planted for one year, the pH value of the soil is 6.8, the soil salt content is 0.13%, the total soil pore space rate is 54%, the soil bulk density is 0.96 g/cm<3>, and the effective nitrogen content in the soil is 40 mg/kg.

Description

technical field [0001] The invention relates to a method for interplanting lettuce and potatoes in saline-alkali land, and belongs to the technical field of saline-alkali land biological improvement. Background technique [0002] Saline-alkali land is a huge potential resource, and the development and utilization of saline-alkali land is one of the important measures to expand the area of ​​cultivated land and further develop agricultural production. There are about 1.5 billion mu of various saline soils in my country, accounting for 26.3% of the world's saline soil area. The area of ​​saline-alkali land in coastal and inland areas is relatively large, and most of the saline-alkali land has been waiting for development. [0003] Planting saline-alkali-tolerant plants in saline-alkali land is an effective method to control saline-alkali land, but the utilization rate of saline-alkali land is low, the economic benefits of planting plants are not significant, and the improvemen...
