Embodiment 1

[0019] Embodiment one, the production of compound fertilizer

[0020] a Stir and mix the mineral fertilizer, organic fertilizer and slow-release fertilizer in proportion;

[0021] Weigh 48 kg of medical stone, 16 kg of calcite, and 16 kg of zeolite in the mineral fertilizer; adjust the following components of organic fertilizer according to seasons and other factors: cow dung, horse manure, chicken manure, humic acid, milk vetch, alfalfa, crushed straw, The proportion of mulch, soybean meal, peanut meal, and the remaining residue of fermentation products is as follows: 20 kg of cow dung, 20 kg of horse manure, 20 kg of chicken manure, 80 kg of humic acid, and milk vetch 30 kg, 30 kg of alfalfa, 30 kg of crushed straw, 30 kg of mulch, 80 kg of soybean meal, 80 kg of peanut meal, and 80 kg of residual residue of fermentation products; slow-release fertilizer is 45 kg of calcium superphosphate, 55 kg of urea formaldehyde; Stir in a blender;

[0022] b Weigh 0.36 kg of microbial...

Embodiment 2

[0026] Embodiment two, the use of micro-moist irrigation system

[0027] When in use, open the valves of the micro-run main pipe and the micro-run branch pipe in advance, and then lay them in the saline-alkali land that needs to be irrigated, and pass the filtered water (to avoid clogging the pipe) into the micro-run main pipe, and the irrigation water flows through the micro-run branch pipes to reach In areas that need to be irrigated, because the micro-moisture branch pipe is wrapped with a semi-permeable membrane and non-woven fabric, the semi-permeable membrane can automatically adjust the irrigation water through the osmotic pressure difference, which has the effect of saving water; the non-woven fabric is to avoid blocking the through hole , while increasing the compressive performance of the wetting branch. When the probe detects abnormal changes in humidity, salinity or PH value in the local space, it can be fed back to the sensor signal control system, so that it can ...

Embodiment 3

[0028] Embodiment three, the plantation of sweet sorghum

[0029] (1) Selection of saline-alkali land

[0030] Select a salinized soil plot with a 0-30cm soil layer with a salt content of 0.8%, a pH of 8.8, a degree of alkalinity of 7-8%, a total soil porosity of 21%, and an air gap of 4%.

[0031] (2) Sowing:

[0032] According to the soil fertility, fertilize 1-3 tons of special compound fertilizer per mu, plow the land deeply, mix the compound fertilizer fully with the soil, flatten the land, dig pits and fill the micro-moist irrigation system in a grid pattern, sow, sow The amount is generally 2.0 kg per mu, and the sowing depth is generally 3-4 cm with a corn no-tillage precision seeder.

[0033] (3) Field management:

[0034] Appropriate dense planting, 6000-8000 seedlings per mu, preferably no more than 10,000 plants, completed once at the 3-5 leaf stage, with a plant spacing of 15-17 cm X 60-70 cm. Tiller removal is not required for silage, but tiller removal is re...

Abstract

The invention discloses a method for planting crops on saline and alkaline land. Compound fertilizer is applied to a saline and alkaline land parcel, deep tillage and flattening are carried out, a pit is dug to bury a micro-moistening irrigation system, and sowing and field management are carried out. Due to the fact that the special compound fertilizer with microbial activity is adopted, fertility can be provided durably, in combination with the micro-moistening irrigation system, automatic hand regulation can be carried out for irrigation, water is saved, and maintenance is convenient. The soil condition of a planting area is effectively improved, the PH value is reduced to 7.2 from original 8.8, the alkalization degree of soil is reduced to about 2.3%, the total pore space rate of the soil is increased to about 52%, and ventilating pores are improved to about 15%. The crops are high in disease resistance and good in growth vigor, and the yield is obviously increased.

Description

technical field [0001] The invention relates to the field of soil improvement in saline-alkali land, in particular to a method for planting crops in saline-alkali land. Background technique [0002] The ecological restoration and improvement of saline-alkali land is a project that benefits the country and the people. It can increase the area of ​​cultivated land, tap agricultural potential, and is more conducive to the development of the agricultural industry. The improvement methods of saline-alkali land generally adopt physical methods, hydraulic methods, chemical methods, and biological methods. Among them, the first three methods require a lot of manpower and material resources, and the fourth method takes a long time and has slow results. [0003] However, using biological methods to restore and improve the ecology of saline-alkali land can best solve the fundamental problem, so there are more researches in this area at present. Breeding saline-alkali-resistant green p...
