High ridge and deep furrow straw covering tillage method for autumn potatoes in semi-late rice field

Abstract

The invention discloses a high ridge and deep furrow straw covering tillage method for autumn potatoes in a semi-late rice field. The high ridge and deep furrow straw covering tillage method comprises the following steps: A), ridging: plotting on a hardened field with rice stubbles, furrowing to make ridges, digging furrows and flattening ridge surfaces; B), base fertilizer applying; C), sowing: sowing two rows on each ridge with a row distance of 45-50cm and a plant distance of 20cm; D) straw covering: covering about 7cm of straws on seed potatoes; E) furrow deepening: hoeing the furrows and moving soil in the furrows to the ridges; F) management: doing well daily management. The procedures of plowing, pit digging and the like can be saved, labor and time are saved, apparent extensive cultivation is intensive cultivation indeed, and the labor is saved by 50% than a conventional cultivation mode. Tillage can be normally carried out in the wet field after the rain so that the farming season cannot be missed. The seed potatoes are sowed on the hardened field with the rice stubbles in a swing way. The coverage of the seed potatoes with the straws preserves moisture, promotes ventilation and is favorable to the growth of potato seedlings. Clumps on the ridge surfaces are spaced by the straws, thereby resisting waterlogging as well as drought.

Description

Technical field [0001] The invention relates to a potato farming method, in particular to a farming method for planting autumn potatoes with rice straw mulching in the middle of the rice stubble in the south. Background technique [0002] In the hilly and mountainous areas of southern my country, rice is no longer planted in autumn after harvest, and only one crop of medium rice is planted throughout the year. The reason why rice and wheat (oil) two crops are rich in temperature and light resources, and the reason why they are not planted in autumn is because of the terraced fields of Wangtiantian. Early spring plowing, gathering spring rain to plant rice, the rice growth period is synchronized with the rainy season, and the stable yield of the rice in the rain is sought, and the stable and high yield is formed, forming a year-round farming system of one-middle rice. Mid-season rice matures around the first ten days of September, which is an ideal planting crop for autumn potato...

Problems solved by technology

[0015] The purpose of the present invention is to overcome the defects of the existing middle rice stubble autumn potato plowing and digging hole planting which is labor-intensive and time-consuming, the season is delayed, and the straw cannot be returned to the field, and to provide a method of covering cultivation with middle rice stubble autumn potatoes in high borders and deep furrows.
