A kind of planting method of winter crop potato

Abstract

The invention provides a planting method of winter crop potatoes, the method is: select the ground, prepare the ground, apply base fertilizer, then process the potatoes into tubers after accelerating germination, sow seeds in two rows with large ridges after seed dressing, and carry out field cultivation after mulching. Management and pest control. In the present invention, after site selection, site preparation and basal fertilizer application, the potatoes are accelerated and processed into potato cubes with 2 to 3 healthy bud eyes, which are sown in double rows on large ridges, and after film covering, the seedlings are replenished in time, weeding and topdressing, In addition, pesticides are used alternately to prevent and control potato late blight, and seedlings are killed during the harvest period, which has a significant effect on increasing production.

Description

technical field [0001] The invention belongs to the technical field of potato planting, in particular to a method for planting winter cropped potatoes. Background technique [0002] Bijie City is located at the junction of three provinces, Yunnan, Guizhou and Sichuan. The territory is karst, with overlapping peaks and ravines. The average altitude is about 1500m, the annual rainfall is about 950mm, the frost-free period is about 260 days, and the average temperature is about 13°C. It provides unique conditions for potato planting. climate conditions. The potato planting area in Bijie City is about 5 million mu. Potatoes have become an important crop after poverty alleviation and the adjustment of the planting industry structure. However, in terms of production, due to reasons such as the lack of in-depth promotion of new varieties and new technologies, the extensive management during the growth period of habitual planting still accounts for a large proportion. After many y...

However, in terms of production, due to reasons such as lack of in-depth and timely promotion of new varieties and new technologies, extensive management during the growth period of habitual planting still accounts for a large proportion

After many years of visits and investigations, the author found the following bottlenecks restricting high and stable potato yields in production: fragmented land, large slopes, and various soil types lead to the inability to popularize small-scale mechanization, resulting in high labor costs; when the stubble is replaced, the land does not reach the depth The degree of intensive plowing leads to the decline in yield and the occurrence of diseases year after year

Growers use their own seeds all year round according to their personal preferences, and the replacement of seed potatoes is not timely, and the treatment measures for sowing seed potatoes are not in place; because it is impossible to distinguish the grade, origin information, and source of seed potatoes with the naked eye, seed potato expansion enterprises In order to obtain subsidies , mixed commercial potatoes are sold as high-generation seed potatoes; planting techniques are extensive and mixed, and growers have a serious "waiting and relying" mentality. Government-led projects or procurement contracts signed with enterprises (professional cooperatives) are basically what type of supply What kind of fertilizer is used for the best fertilizer, and it is not adapted to local conditions. The fertilization concept of "what is lacking and what is supplemented" has been adopted. It has always been a habitual planting method of insufficient fertilization, single, and no fertilization in the middle and late stages of the growth period; Awareness is weak, high temperature and continuous rainfall create good conditions for the occurrence of diseases, and there is no comprehensive prevention and control measures and combination of chemicals, resulting in higher and higher cost of prevention and control, and low control efficiency and enthusiasm
