Problems solved by technology

These provide an effective guidance for the planting of winter crop potatoes, but they cannot solve the technical problems of planting in frost areas
[0003] The production area of ​​potato winter cropping areas in Yunnan Province is expanding year by year, and more and more frost areas are used for planting winter crop potatoes. In addition, box crop production is mainly used all year round, which suffers from different degrees of frost damage, which seriously affects potato production.
Frost prevention and control measures applied to winter crop potato production include mulching film, frost prevention sheds, spraying antifrost agents and other measures, but these measures increase production input costs, but fail to achieve better control effects

Embodiment Construction

[0020] The technical solution of the present invention will be further described below in conjunction with the examples.

[0021] A comprehensive frost-proof cultivation method for winter cropping potatoes, comprising the following steps:

[0022] (1) Land selection and land preparation: Select a sandy loam block with a suitable climate and no frost, sufficient water sources, convenient irrigation and drainage, sufficient manpower, loose and slightly acidic structure, plow the land with a large tractor, and then use an improved tiller to open the ditch, with a row spacing of 80cm ;

[0023] (2) Determine the planting time: reasonably select the planting time according to the frost period and the production planting period, and control the planting time one month before the frost period;

[0024] (3) Seed potato treatment: After the seed potato breaks dormancy and germinates, the principle of cutting the seed potato is to use the top advantage as much as possible to ensure tha...

Abstract

The invention discloses a method for comprehensive frost-prevention cultivation of winter-cropping potatoes. The method for the comprehensive frost-prevention cultivation of the winter-cropping potatoes comprises the following steps of (1) land selection and preparation, (2) planting time confirming, (3) seed potato proposal, (4) fertilizer application and seed sowing, (5) earth covering and fertilizer application, (6) field management, (7) harvesting. The method for the comprehensive frost-prevention cultivation of the winter-cropping potatoes has the advantages of being obvious in effect, simple in operation, low in cost and high in yield and reducing the pesticide using amount and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a comprehensive frost-proof cultivation method for winter cropped potatoes. Background technique [0002] Potato planting technology is directly related to potato yield, control of diseases and insect pests, etc. The contribution of winter cropping potato planting technology to yield is more prominent. There have been some studies on the planting technology of winter crop potatoes. For example, in 2011, Feng Shaohui and others applied for the planting of winter crop potatoes in areas with suitable climate (no frost), sufficient water source, convenient drainage and irrigation, sufficient manpower, loose and slightly acidic sandy loam soil. technology patent. Dai Hengren and others studied the effects of varieties and agronomic measures on the frost resistance of southern potatoes, and found that varieties and cultivation measures have a significant effect on yield, and t...
