Embodiment 1
[0047] A drought-resistant, salt-alkali-resistant, high-yield, high-efficiency cultivation method for cotton adopts the following technical scheme:
[0049] Step 2: Soil preparation and fertilization: mechanical plowing and plowing, before plowing, cotton stalks should be removed. 10d to 15d before sowing, when the relative water content of the soil plow layer is less than 70%, it is necessary to irrigate artificially to create moisture. During the suitable tillage period, the soil should be plowed loose and leveled with harrows. The soil in the plow layer should meet the standards of flat ground, broken soil, sufficient moisture, no residues and sundries, and empty top and bottom solid.
[0050] The application of base fertilizer is mainly based on the demand of cotton. According to the principle of combinin...

[0078] Embodiment 2, the technical scheme of the present invention and existing flood irrigation, the comparative test difference of artificial operation cultivation on concrete technical scheme
[0079] (1) Technical input
[0080] 1. Fertilizer application
[0081]The traditional planting technology and the drought-resistant, salt-alkali-tolerant, high-yield and high-efficiency cultivation method use the same base fertilizer, both of which are 15kg / mu of diammonium phosphate + 3kg / mu of potassium sulfate. The traditional planting technology topdressing urea 35kg / mu + potassium sulfate 12kg / mu, a single fertilization amount is large, the fertilizer utilization rate is low, and the fertilizer efficiency is poor. Drought-resistant, saline-alkali-tolerant, high-yield and high-efficiency cultivation methods apply urea 20kg / mu + potassium sulfate 10kg / mu as topdressing, follow the principle of small amount and multiple times, the fertilizer goes with the water and stays around th...

Abstract
The invention discloses a drought-resistant saline-alkaline-tolerant high-yield efficient cultivation method for cotton. The drought-resistant saline-alkaline-tolerant high-yield efficient cultivationmethod sequentially comprises the steps: selecting and preparation soil; applying a base fertilizer; cutting and treating seed potatoes; carrying out ridging and shaping; carrying out sowing and paving a drip irrigation pipeline; and mulching a film and fully covering soil with the thickness of 5-7cm, wherein the soil covering is best performed on the sowing day or is centrally finished within 5-7d after sowing; and field management comprises water irrigation, topdressing, pest prevention and control and the like. Due to the adoption of the method for fully covering soil on a mulching film after sowing, the fertilizer and water condition of the soil is effectively improved; the effects of preventing high wind from breaking the mulching film in spring and inhibiting grass growth on a ridged surface are achieved; and compared with a method by which soil covering is not needed and the film is artificially broken to release seedlings, the method has the advantages that the ground temperature can be raised by 2-3 DEG C, seedlings are emergent 5-7d beforehand, and cotton can be harvested 7-12d beforehand. In addition, potatoes can voluntarily break a film and come up out of the ground,and artificially breaking the film to release the seedlings is not needed, so that manpower is greatly saved, the operation cost is reduced, and the economic benefit of the potato production is increased.
Description
technical field [0001] The invention relates to a crop cultivation method, in particular to a drought-resistant, salt-alkali-tolerant, high-yield, high-efficiency cultivation method for cotton, and belongs to the technical field of plant cultivation. Background technique [0002] Cotton is one of the most important fiber crops in the world. As a strategic material, it plays a pivotal role in the national economy. Cotton has important uses in textiles, national defense, medicine, automobile industry, etc., and its seeds are not only important oil crops, but also an important food and feed resource. It is a new type of food that integrates grain, cotton, oil, feed, and medicine. High-efficiency economic crops are related to the national economy and people's livelihood. It can be said that the production, circulation, processing and consumption of cotton are closely related to the development of the national economy. my country is the largest raw cotton producer and also the l...
