Problems solved by technology

[0002] At present, most of the irrigation areas are covered with film in spring. At this time, there is a lot of wind and sand, and the evaporation is large. However, furrow irrigation with ridge film or full film double ridge furrow irrigation is easy to cause soil loss due to factors such as loose soil and slow film mulching speed during ridge operation. However, incomplete germination occurred

Embodiment 1

[0030] Embodiment 1-taking corn planting as an example

[0031] 1-Site selection and preparation: choose loamy soil and sandy loam soil with deep soil layer, loose soil quality, medium fertility and not easy to harden. Gramineae, beans, and potatoes are the best crops in the previous crop, and corn can also be cropped continuously, but it is best to rotate crops once every three years. After the previous crops are harvested, deep plow and sun-dry, timely harrowing to preserve moisture and suppress. Use a rotary tiller before sowing with plastic film to ensure that the soil particles are finely divided, the residual roots and branches and leaves are small, and the ground is flat and free of rubbish.

[0032] 2- Fertilization and soil treatment: 60,000 kg / hm of high-quality agricultural fertilizer combined with rotary tillage before sowing 2 , DAP 450 kg / hm 2 , urea 300 kg / hm 2 , zinc sulfate 30kg / hm 2 . Before coating, 40% beta-thrax wettable powder 750 g / hm 2 , or A. B....

Embodiment 2

[0040] The difference from Example 1 is that the fertilization and soil treatment steps apply high-quality agricultural fertilizer 40000 kg / hm before sowing 2 , DAP 500kg / hm 2 , urea 350 kg / hm 2 , zinc sulfate 40kg / hm 2 .

Embodiment 3

[0042] The difference from Example 1 is that in the water and fertilizer management step, 350 kg / hm of urea is applied in combination with irrigation 2 ; Irrigate with diwater during the peak period of corn tasseling leaves, and apply 500kg / hm of urea in combination with the irrigation water 2 After 20 days, water three times, and then water four times according to the precipitation. Each irrigation volume should be controlled at 1000 m 3 / hm 2 .

Abstract

The invention discloses a sandy-loam complete-membrane laying and soil-covering planting method for crops, and belongs to the field of planting of crops. The sandy-loam complete-membrane laying and soil-covering planting method for crops comprises the following steps: land selection, soil preparation, fertilizer application, film covering and soil covering, seed sowing, seedling management, water and fertilizer management, pest control and harvesting. The step of soil preparation particularly comprises the following specific substeps: carrying out deep ploughing and drying the earth which has been ploughed up in the sun after preceding crops are harvested, harrowing, leveling and retaining water in time and pressing soil, carrying out rotary tillage and flattening the ground. The step of membrane covering and soil covering comprises the following specific substeps: covering the land with mulching films with the thickness of 0.008-0.01 mm and covering the land with soil at a time, using a caterpillar type conveying film covering and soil covering machine, and flatly laying the mulching films on the whole ground, wherein the thickness of covered soil is 0.5-1.5 cm, the mode of furrowing to press the films is omitted, the latter film is closely connected with the former film, gaps do not exist, and the films are not overlapped. The complete-membrane laying soil-covering planting method is used, by the water retaining and temperature increasing effect of the mulching films, the yield of the unit area is greatly increased, and furthermore, the crop planting adaptability is greatly improved.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a sandy loam soil crop planting method. Background technique [0002] At present, most of the irrigation areas are covered with film in spring, when the wind and sand are strong and the evaporation is large. However, furrow irrigation with ridge film or full film double ridge furrow irrigation is easy to cause soil loss due to factors such as loose soil and slow film mulching speed during ridge operation. However, the phenomenon of incomplete emergence appeared. Contents of the invention [0003] The purpose of the present invention is to provide a method for planting sandy loam crops with full-film flat-covered soil. [0004] The technical scheme of the present invention is as follows: a method for planting crops in sandy loam soil with full-film flat-covering and soil-covering, including the steps of site selection, site preparation, fertilization, film-covering, sow...
