Embodiment 1

[0028] A method for planting castor in saline-alkali land in arid areas, carried out according to the following steps:

[0029] A. Use deep plowing to plow and level the soil, and the plowing depth is 20-30cm;

[0030] B. Sprinkle superphosphate in the field, plow again, level off, dig ridges and sow. The height of the ridge is 25cm, and the width of the ridge is 150cm;

[0031] C. Plant 2 rows of castor oil on the ridge, the hole distance is 25-30cm, and 2 grains per hole; put urea and microbial fertilizer in the hole before sowing, and put earthworms; after sowing, cover the ridge with two layers of hollow blocks for recycling The lower layer is small particles with a particle size of 1-3mm, and the upper layer is large particles with a particle size of 3-8mm;

[0032] D, add microbial fertilizer and water regularly until castor-oil matures;

[0033] E, harvest the mature castor-oil plant;

Abstract

The invention provides a method for planting ricinus communis in a saline and alkaline land in a drought region. According to the method, the pH value of soil is improved with the combination of a microbial fertilizer, earthworms and calcium superphosphate, and fertilizers are provided for ricinus communis to grow; due to adoption of recycled building materials, the moisture utilization rate can be increased; with the combination of ricinus communis planting and saline and alkaline land improvement, the yield of the ricinus communis can be increased year by year.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for planting castor in saline-alkali land in arid areas. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized soil in my country i...
