Embodiment Construction

[0043] Below in conjunction with embodiment the present invention is further described.

[0044] The water-saving, drought-resistant and high-yield cultivation method for whole potato sowing in the hilly and sloping land of northwest Shanxi comprises the following steps:

[0045] S1 Soil preparation and fertilization

[0046] In autumn, deep plowing is required to increase the active soil layer, with a deep plowing depth of 25-30cm, to store water and fertilizer; apply 2500kg of farmyard manure, and plow into the soil with deep plowing in autumn;

[0047] Application of inorganic fertilizers: Nitrogen fertilizer application amount is converted to pure N10~12kg, K fertilizer application amount is converted to pure potassium 5~8kg, P fertilizer application amount is converted to pure phosphorus 3~5kg;

[0048] In order to make the plants grow strong, the root system strong, and the tubers large and numerous, deep plowing is required in autumn to increase the active soil layer, ...

Abstract

The invention discloses a whole-potato-seeding based water-saving drought-resistant high-yield cultivation method for hill sloping fields in the northwest of Shanxi province, and belongs to the technical field of crop cultivation. The method includes the steps of soil preparation, fertilization, preparation before seeding, seeding in proper time, growing period management and the like. The method further includes reasonably distributing water and fertilizer, managing herbicide and the like and seeding based on whole potatoes. Through whole-potato-based seeding, normal seeding and germinating can be realized without rainfall; the whole potatoes are not easy to infect by germs in the soil as having no cut, and virus infection caused by non-strict cutter sterilization can be avoided; the fertilization mode, the weeding mode and the pest prevention mode of the method are applicable to potato planting in the northwest of the Shanxi province, utilization rate of phosphatic fertilizer is increased, manual weeding is omitted, labor saving effect is achieved, and effective insect disease prevention can be realized; the yield of potatoes can be increased by 20-60%.

Description

technical field [0001] The invention relates to a crop cultivation method, in particular to a water-saving, drought-resistant and high-yield cultivation method for sowing whole potatoes in hilly and sloping land in northwest Shanxi. Background technique [0002] Shanxi Province is a major province of potato production. As one of the main economic crops, the sown area of ​​potato has increased from 193,000 ha in 2009 to 2 Restored to 240,000 hm in 2012 2 Around this time, the regional distribution of potato production took shape. Potato planting area in Shanxi Province reaches 3333hm 2 The above-mentioned main producing counties have reached 20, basically forming the three major potato industrial belts of Yanmenguan, Taihang Mountain and Luliang Mountain. However, the main potato production areas are mostly distributed in mountainous and hilly areas, where the natural conditions for production and irrigation conditions are relatively poor, and the annual precipitation is b...
