Potato planting method

Abstract

The invention provides a potato planting method. The potato planting method comprises the following steps: A, conducting treatment before sowing, specifically, deeply ploughing soil and applying a first organic fertilizer to the soil; B, conducting sowing treatment, specifically, mechanically sowing the disinfected and diced seed potato blocks, and applying a high-nitrogen high-potassium compound fertilizer, a second organic fertilizer and a herbicide; C, conducting film mulching and shed building, specifically, building an arched shed after film mulching; and D, conducting field management, specifically, after the sown potato seeds emerge, breaking a film to guide seedlings, then conducting field management on potato seedlings, wherein field management includes temperature ventilation management, water and fertilizer management and disease and pest control, and the water and fertilizer management includes the step of spraying a phosphorus-potassium foliar fertilizer when the potatoes grow to a ridge sealing period. The method has the beneficial effects that the harvesting time of potatoes can be further advanced, the yield is ensured, the operation is more convenient, the use amount of a compound fertilizer is reduced, the labor cost is further saved by adopting mechanical sowing, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a potato planting method. Background technique [0002] Potato has the characteristics of wide adaptability, high nutritional value, great potential for increasing production, high comparable benefits, and wide range of uses. It has become the fourth largest food crop in China, with a planting area of ​​about 84 million mu, ranking first in the world. With the continuous adjustment of the agricultural industry structure, the potato industry has developed rapidly, and the planting area has continued to increase. Potatoes have become an important economic crop, and the early release of potatoes is conducive to increasing economic income. [0003] At present, in order to let potatoes go on the market early, after the seed potatoes are planted, they are covered with plastic film. For example, Shan Hong, Song Jianjun, Qi Yunlin, etc. have adopted the cultivation technology method ...

AI Technical Summary

Problems solved by technology

However, under the premise of only plastic film for heat preservation, the heat preservation is not sufficient in the extreme low temperature rainy and snowy weather in winter and the late spring cold period, and the seed potatoes and seedlings are often frozen.

Moreover, the traditional fertilization method needs to topdress a large amount of nitrogen and potassium fertilizers. However, due to the limitation of plastic film, ordinary fertilization methods cannot be used. Generally, drip irrigation is used to apply water-soluble fertilizers to meet the fertilizer requirements of potatoes in the later stage under the limitation of plastic film, that is, fertilizer and water. must be administered later

This cultivation method is very suitable for cold and dry climate areas in winter, but in the subtropical monsoon climate where there is little difference between dryness and humidity in winter and summer, the water will be excessive, which will easily cause tuber rot and field diseases, which will affect its quality and yield.
