Intercropping of Chinese Yam and Potato Covered with Straw in Spring and Autumn

Abstract

The interplanting of Chinese yam and potato covered with rice straw in spring and autumn is characterized by the following steps: a. Before planting spring potato, lay the film groove for planting Chinese yam, fill in the carbonized rice husk, and cover the soil layer; b.2 In the month, potatoes were planted on the yam border using the straw-covered potato planting technique; c. In April, the yam seedlings were planted on the membrane grooves to grow together with the potatoes; d. The potatoes were harvested in the middle and late May, and the yams continued to grow on a scaffold; e. In mid-August, another season of straw-covered potatoes is planted on the yam border, and yams and potatoes are harvested at the same time from late October to late November.

Description

Technical field:

[0001] The invention relates to the field of agriculture, forestry and horticulture, in particular to a new technology for planting yams and potatoes, specifically interplanting yams and potatoes covered with straw in spring and autumn. Background technique:

[0002] Traditional yam planting or ditching or drilling is time-consuming, laborious, and labor-intensive, and the selection of land is also harsh. It is required that the groundwater level is lower than 1 meter and the soil layer is deep. The gravel soil cannot be planted, nor can it be replanted. The yam tubers grow deep, and the harvesting is labor-intensive and easy to damage the tubers. It is also very labor-intensive during harvesting. A strong labor force can only harvest 3 centimeters a day at most. Above these, have increased the plantation cost of yam greatly, have also hindered the development of yam industry.
