High-yield and early-maturity cultivation method of ecological brewing heat for potatoes

Abstract

The invention discloses a potato ecological heat brewing high-yield and early-maturing cultivation method, which comprises the following specific steps: plowing, sun-drying and freezing the fields for potato planting in a greenhouse in advance; planting according to the planned ridge width and ridge width Ditching machine is used for ditching at intervals; after ditching, harmless and decomposed farmyard manure, potassium sulfate compound fertilizer and a large amount of element fertilizer are evenly spread in the ditch, and then the seed potatoes that have been cut into pieces and sterilized are placed in the ditch. Place seeds in the ditch; use crushed crop straw to cover the potato cultivation ridge twice; break the membrane in time after potato emergence, and seal the membrane mouth tightly with soil; use drip irrigation to control the water content of straw in the membrane; after potato emergence, control the shed Internal temperature; After the potatoes are formed, the plastic film is removed from both sides of the cultivation ridge, and the straw mulch is removed to harvest potato tubers that meet the size of the commodity.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a potato cultivation method, in particular to a potato ecological heat brewing high-yield and early-maturing cultivation method. Background technique [0002] The nutritional value of potato protein is very high, and its quality is equivalent to that of eggs. It is easy to digest and absorb, and it is better than the protein of other crops. Potato has short growth cycle, strong adaptability, high yield per unit area, rich tuber nutrition and wide application. It is the fourth largest food crop in the world after rice, wheat and corn. [0003] The traditional cultivation method of potatoes is to plow the land deeply before sowing, level it again, and apply base fertilizer at the same time; It is necessary to carry out 2 to 3 times of cultivating and cultivating the soil; when harvesting, the soil must be turned over and the potatoes shall be dug out one by one. The disadv...

Problems solved by technology

The disadvantage of this cultivation method is that the potatoes form tubers in the soil, and when the tubers expand, they are squeezed by the soil, which is not conducive to the expansion of the tubers. In the case of non-sandy loam, the resistance they receive is greater. Generally, the tubers are relatively small, large and medium-sized. The potato rate is low, and the planting method is complicated to operate, labor-intensive, and labor-intensive

[0004] The current conventional planting methods of potatoes have the following deficiencies: the conventional planting methods have stricter requirements on the soil, generally sandy soil or loamy soil is suitable, and potato planting cannot be carried out if the soil is relatively sticky.

With the conventional planting method, the potato growth period is short, and the potato is harvested at one time, which often has the problem of low yield
