Three-dimensional cultivating method of potato and corn in dry land

Abstract

The invention provides a three-dimensional cultivating method of potato and corn in a dry land and belongs to the three-dimensional cultivating mode technology of crops. In the method, two crops are planted in the same field land along an east-west direction long row in a strip field band shape, a plant band is formed in 140cm width, and two rows of potato are planted in an occupied area of 65 cm width; in the two rows, the row spacing is 40 cm, and the plant spacing is 25cm; film covering is timely carried out after spring sowing is carried out; after the potato is sprouted and when the seedling is abut against the film, the film can be destroyed, and the seedling can be exposed and then is tightly covered and sealed by using soil in a ditch; in the end of March, two rows of early-maturing special corns are planted at the margin of the potato planting soil in 75 cm width; in the two rows, the row spacing is 50cm, and the plant spacing is 30cm; the seedling density per mu is 4000 plants; and after the corn is sprouted and when the seedling is abut against the film, the film can be destroyed, and the seedling can be exposed and then is tightly covered and sealed by using soil in the ditch. Compared with the prior art, the method provided by the invention has the three-dimensional, early-maturing, high-yield and efficient effects; and by using the method, the load of labors can be lightened, the requirement on the labors is reduced, the growth periods of the potato and corn are shortened, and the utilization rate of the soil is improved.

Description

technology field; [0001] The invention belongs to the three-dimensional cultivation mode technology of crops, and in particular relates to a strip cultivation method for two kinds of crops, potato and corn. Background technique: [0002] Traditional potato monoculture is planted in spring and harvested in summer and autumn. Because potatoes are cool plants with short days, the yield is easily affected by the local natural climate, temperature rise, and strong light. Generally, the yield per mu is about 500 kg. Field spring corn in the north is generally sown evenly in narrow rows with a row spacing of 70 cm and a plant spacing of 40 cm, with about 3,000 seedlings per mu. Because maize is a plant with tall stalks and large rows, the traditional planting methods cause individual advantages to be affected by the mutual constraints of high temperature and strong sunlight in the field, and cannot scientifically maximize the advantages of individuals.

Problems solved by technology

Because corn is a plant with tall stalks and large rows, the traditional planting method causes individual advantages to be affected by the common mutual constraints of high temperature and strong sunlight in the field, and cannot scientifically maximize the advantages of individuals.
