Ecological fermentation high-yield early-maturing culture method for potato

Abstract

The invention discloses an ecological fermentation high-yield early-maturing culture method for a potato. The method comprises the following specific steps: ploughing a field block prepared for planting the potato in a greenhouse, sunning and freezing the upturned soil for later use; using a ditcher to ditch according to the planned planting ridge width and the ridge space; evenly applying a harmless treatment decomposed farmyard manure, a potassium sulphate compound fertilizer and a large quantity of element fertilizer in a ditch after ditching, placing and planting the diced and disinfected potato in the ditch; secondarily covering a potato culture ridge with a crushed crop straw; timely breaking a film and releasing a seedling after the potato seedling emerges, tightly sealing a film opening with soil; controlling the water content of the straw in the membrane through drop irrigation; controlling the temperature of the greenhouse after the potato seedling emerges; uncovering the film from the two sides of the culture ridge after a potato tuber forms, and pushing the straw mulch aside to harvest the potato tuber meeting the requirement of the product size.

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
