Problems solved by technology

[0003] The current hilly and dry land areas are limited by light and heat resources. The main cultivation mode is one crop per year, that is, only one crop of winter wheat or summer corn (including silage) is planted a year. The serious waste of rainfall and light energy makes continuous cropping difficult and the yield rate per unit area of ​​land is low

Embodiment 1

[0025] A two-year three-ripening water-fertilizer efficient cultivation method for food crops in hilly dry land, comprising the following steps:

[0026] The first step is to select the land for planting: measure the water content and nutrient element content in the soil, and measure the soil depth to 15cm;

[0027] The second step, fertilization for site preparation: apply a sufficient amount of base fertilizer at one time, the fertilizer applied is organic fertilizer (cattle, sheep manure) 1 ton / mu, nitrogen, phosphorus and potassium compound fertilizer 15 kg / mu, and apply the base fertilizer to the depth of the soil 15cm;

[0028] The third step is to sow summer corn: in mid-April, film-covered summer corn is planted, and the corn is broadcast live with wide rows and double-grain mechanization. For 30 kg of multi-element fertilizer, the first fertilization is carried out at the 5-leaf stage of corn, and 35% of the total fertilization amount per mu can be applied; the secon...

Embodiment 2

[0032] A two-year three-ripening water-fertilizer efficient cultivation method for food crops in hilly dry land, comprising the following steps:

[0033] The first step is to select the land for planting: measure the water content and nutrient element content in the soil, and measure the soil depth to 16cm;

[0034] The second step, fertilization for site preparation: apply a sufficient amount of base fertilizer at one time, the fertilizer applied is organic fertilizer (cattle, sheep manure) 1 ton / mu, nitrogen, phosphorus and potassium compound fertilizer 15 kg / mu, and apply the base fertilizer to the depth of the soil 16cm;

[0035] The third step is to sow summer corn: in mid-April, film-covered summer corn is planted, and the corn is broadcast directly in wide rows and double-grain mechanization. For 32 kg of multi-element fertilizer, the first fertilization is carried out at the 5-leaf stage of corn, and 35% of the total fertilization amount per mu can be applied, and the...

Embodiment 3

[0039] A two-year three-ripening water-fertilizer efficient cultivation method for food crops in hilly dry land, comprising the following steps:

[0040] The first step is to select the land for planting: measure the water content and nutrient element content in the soil, and measure the soil depth to be 18cm;

[0041] The second step, fertilization for site preparation: apply a sufficient amount of base fertilizer at one time, the fertilizer applied is organic fertilizer (cattle, sheep manure) 1 ton / mu, nitrogen, phosphorus and potassium compound fertilizer 15 kg / mu, and apply the base fertilizer to the depth of the soil 18cm;

[0042] The third step is to sow summer corn: in mid-April, film-covered summer corn is planted, and the corn is broadcast directly in wide rows and double-grain mechanization. It is 35 kilograms of multi-element fertilizers. In the third step, fertilization is carried out for the first time at the 5-leaf stage of corn, and 35% of the total fertilizatio...

Abstract

The invention discloses a two-year triple-cropping water and fertilizer efficient cultivation method for grain crops in hilly and dry land. The method comprises the following steps of 1, selecting planting land, namely measuring the water content and the nutrient element content in soil, and measuring the soil depth to be 15-30cm; 2, performing soil preparation and fertilization, namely applying enough base fertilizer at a time with the amount of 1 ton / mu of organic fertilizer (cow and sheep manure) and 15 kg / mu of nitrogen-phosphorus-potassium compound fertilizer, and applying the base fertilizer to the soil with the depth of 15-20 cm; and 3, sowing summer corn, namely sowing the summer corn in a film mulching manner in the middle ten days of April, directly sowing the corn by adopting wide-row double-grain mechanization with the plant number of 4000-4500 per mu, the plant spacing of 25-35cm and the row spacing of 35-45cm, and additionally applying multi-element fertilizer with the fertilizing amount of 30-45 kg per mu in the last ten days of June. According to the method, land, light, heat, water and other resources are fully utilized, the land utilization efficiency is improved, the grain yield is increased, the input cost is fully reduced, resource waste is effectively avoided, and the water and fertilizer effects are fully played to increase the grain yield.

Description

technical field [0001] The invention relates to the technical field of grain cultivation in hilly dry land, in particular to a two-year and three-ripening water-fertilizer efficient cultivation method for grain crops in hilly dry land. Background technique [0002] In some hilly and dry land areas in my country, the crops are winter wheat, sorghum, and corn (including silage). Winter wheat is an important ration crop. The growth period is from September to October to June to July of the following year, and the growth period of sorghum is from June to October. Due to the vigorous development of the breeding industry, corn is currently an important feed crop, and the sown area is increasing year by year, and its growth period is from April to September. [0003] The current hilly and dry land areas are limited by light and heat resources. The main cultivation mode is one crop per year, that is, only one crop of winter wheat or summer corn (including silage) is planted a year. ...
