Problems solved by technology

[0006] The purpose of the present invention is to solve the above-mentioned problems and provide a method for cultivating crops in dry land covered with ridges (wide width) in furrows. According to the principle of mulching suppression of steaming and ridges and furrows for harvesting rain, crop straws are used as raw materials instead of mulch. Green cover, which solves the problem of water shortage during the growth period of dryland crops

Embodiment 1

[0043] Wheat in the control group: the cultivation method is conventional drill sowing, the row spacing is 15cm, and the seeding rate per mu is 12.5kg.

[0044] Field management techniques are:

[0045] Topdressing fertilizer: Wheat enters the jointing stage, combined with rainfall, topdressing urea 8.0kg per mu.

[0046] Pest control: 100g of potassium dihydrogen phosphate, 50mL of 20% triadimefon EC, 200g of urea mixed with 30kg of water are used for foliar spraying per mu. Generally, winter wheat is sprayed three times, and spring wheat is sprayed twice to control pests and diseases, grow roots and leaves, and promote grain weight gain.

Embodiment 2

[0048] A method for cultivating crops sown in ridges and side furrows covered with straw in dry land, comprising the following steps:

[0049] (1) Fertilization for soil preparation: select a flat plot and apply base fertilizer in combination with deep plowing before sowing. The base fertilizer per mu includes 4000 kg of organic fertilizer, 8.0 kg of pure nitrogen, 8.0 kg of phosphorus pentoxide, and 4.0 kg of potassium oxide;

[0050] (2) Ridging: Ridges are formed at equal intervals in a flat field by machinery to form ridges and furrows, and the ridges and furrows are arranged at intervals. Ridges with a width of 22 cm and a height of 8 cm form a furrow with a width of 12 cm between the ridges. , width 34, straw covered ridge width 22cm + ditch width 12cm;

[0051] (3) Covering straw: crush the straw into 2-4cm finely crushed straw, and evenly cover the finely crushed straw on the ridge surface, and the straw covering amount is 400kg / mu, and the straw covering thickness is ...

Embodiment 3

[0079] Flax in the control group: the cultivation method is wide-width uniform sowing, the sowing width is 15 cm, the width of the width is 15 cm, and the sowing rate is 5.0 kg per mu.

[0080] Field management techniques are:

[0081] Topdressing fertilizer: when the plant height of flax is 15cm-20cm, combined with rainfall, topdress 8.0kg of urea per mu. In the green fruit stage of flax seeds, 150g of potassium dihydrogen phosphate can be used per mu, plus 200g of urea, and 30kg of water can be used for foliar spraying once or twice.

[0082] Pest control: The main diseases include blight, anthracnose, fusarium wilt, powdery mildew, etc. The main pests include cutworms, grubs, aphids, leafminers, oil spills, etc., and are controlled according to the requirements of the agricultural industry standard NY / T1276 .

Abstract

The invention discloses a straw mulching ridge-side (wide) furrow sowing crop cultivation method for dry land, and relates to the field of crop cultivation. The method is characterized by comprising the following steps: (1) land preparation and fertilization: selecting flat plots, and applying base fertilizer in combination with deep ploughing and land preparation before sowing; (2) ridging: carrying out ridging at equal intervals by machinery in a flat field to form ridges and furrows, and arranging the ridges and the furrows in a spaced manner; (3) straw mulching: uniformly mulching ridge surfaces with crushed straw; (4) sowing: performing strip sowing or wide uniform sowing on crops in ridge side furrows, and properly increasing density; and (5) field management: carrying out fertilizerdressing, pest and disease control and returning straw to the field after mulching. The crop straw is used as a raw material to replace mulching films for green mulching according to mulching evaporation inhabitation and ridge and furrow rain collection cultivation principles, the functions of collecting rain to preserve soil moisture and resisting drought to increase yield are achieved, and theproblems that dry crops lack water in a growth period and are low and instable in yield are effectively solved.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for cultivating crops in furrows covered with ridges (wide width) in dry land. Background technique [0002] One of the biggest problems faced by agricultural production is water shortage in the dry agricultural areas of northern China, especially the arid, semi-arid, semi-arid, semi-humid and semi-arid areas (dry land) with precipitation of 250-600 mm, which is manifested as: One is the lack of rainfall; the other is the lack of effective water sources; the third is that the evaporation is too large, often greater than the rainfall, leading to drought, and this part of the ecosystem is very fragile. The traditional way to prevent water evaporation is to cover the plastic film. As an important agricultural material, the polyethylene film has played a very important role in increasing the grain production in the north. However, due to the non-degradability of polyethylene...
