Deep-ditch high-ridge full-film-mulching cultivation method

Abstract

The invention belongs to the technical field of planting, and discloses a deep-ditch high-ridge full-film-mulching cultivation method. The deep-ditch high-ridge full-film-mulching cultivation method comprises six links of region selection, variety selection, formula fertilization, standard sowing, scientific management and timely harvesting. The key point is that a ridging mode (single rows, highridges, deep ditches and full coverage) is reformed through plastic film mulching; 1, the growth period in southern China is short, so that small ridges and single rows (the ridge width is about 70 cm) are popularized, the spatial distribution uniformity of plants is improved, early row sealing is carried out, and the light energy utilization rate is improved; 2, high ridges (the ridge height is 30-35 cm) are manufactured, the thickness of a plough layer is increased, the soil permeability is improved, the root growth environment is improved, a potato tuberization layer is located at the bottom of a ditch, and the phenomenon of soaking in rainy days is eliminated; 3, the ditch is deep, narrow and straight, the ditch bottom is flat, drainage is smooth, and the morbidity is reduced; and 4, mulching film full coverage is carried out, the temperature can be increased, soil moisture and fertility are preserved, and the weeding effect is improved.

Description

technical field [0001] The invention belongs to the technical field of planting, and mainly relates to a deep ditch and high ridge fully film-covered cultivation method. [0002] technical background [0003] At present, the potato is the fourth largest food crop in the world. It is used as grain, vegetable, feed and industrial raw materials. It is rich in nutrients, has a wide range of suitable planting areas, great potential for increasing production, a long industrial chain, and high comparable benefits. my country has become the largest potato producer in the world. Potatoes are also the fourth largest food crop in my country. The annual planting area is more than 80 million mu, the total output is more than 80 million tons, and the average yield of fresh potatoes is about 1000 kilograms per mu. Safety and increasing farmers' income are very important, and the development of potato production also has great strategic significance for promoting modern agriculture. First, i...

Problems solved by technology

[0006] (1) The existing potato cultivation method is not suitable for the climate of dry winter and spring flood in the south; and the planting yield is low

[0007] (2) There are too many idle fields in winter in the south, and the utilization rate of fields and tidal flats is not high; the winter crop structure is single
