High-yield cultivation method for north potatoes through drip irrigation under mulch

Abstract

The embodiment of the invention provides a high-yield cultivation method for north potatoes through drip irrigation under mulch, and relates to the field of potato cultivation. The water utilization rate and the fertilizer utilization rate can be improved, and the yield of the potatoes can be increased in a multiplied mode. The method comprises the steps of soil selection and preparation, drip irrigation system installation, variety selection and potato seed processing, sowing, irrigation, top application, fertilization management and field management. According to the irrigation standard, the field capacity in the germination period ranges from 60% to 65%, the field capacity in the seedling period ranges from 65% to 70%, the field capacity in the tuber forming period ranges from 75% to 80%, the field capacity in the tuber expanding period ranges from 75% to 80%, the field capacity in the starch accumulating period ranges from 60% to 70%, the irrigation norm of the total growth period of the potatoes cultivated through drip irrigation under the mulch ranges from 80 m<3> / 667 m<2> to 120 m<3> / 667 m<2>, the dissolubility fertilizer is selected during the top application, a differential pressure type fertilization tank is adopted, and dressing of 15 kg / 667 <2> of urea during irrigation is carried out.

Description

technical field [0001] The invention relates to the field of potato cultivation, in particular to a high-yield cultivation method for northern potatoes by drip irrigation under film. Background technique [0002] Potatoes are important food crops and economic crops in the north, and 80% of the production areas are distributed in arid and semi-arid economically underdeveloped hilly areas. Drought is the biggest obstacle restricting the increase of potato production in the northern region. Traditional farming depends on the weather for water use, cannot effectively use limited water resources, cannot balance the supply of nutrients, and the utilization rate of fertilizers is extremely low, resulting in low yields of potatoes. inefficient. Contents of the invention [0003] The embodiment of the present invention provides a high-yield cultivation method of drip irrigation under mulch film for northern potatoes, which can improve the water utilization rate and fertilizer util...
