Embodiment Construction
[0033] Aiming at the problems existing in the prior art, the present invention provides a deep ditch and high ridge fully film-covered cultivation method. The present invention will be described in detail below in conjunction with the charts.
[0034] Such as figure 1 As shown, the deep ditch and high ridge full film-covering cultivation method provided by the embodiment of the present invention comprises the following steps:
[0035] S101: Through field soil and environmental surveys, determine suitable application areas; select suitable fine varieties with early maturity, high yield, high resistance, good commerciality, short grape stems, and concentrated tubers.
[0036] S102: Through soil sampling and testing, understand the current situation of fertilization, determine the nutrient status of cultivated land soil, formulate fertilization plan and increase the application of organic fertilizer.
[0037] S103: Through mulching, scientifically reform the ridge-making model, ...

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...
