Sowing method of No-tillage cultivation of Potato covered with Straw
There are three main sowing methods of potato straw mulching no-tillage cultivation:
1. Directly plant rice straw
No tillage in paddy field, digging high-yield ditch (irrigation ditch), ditch width 20 cm, depth 15 cm, ridge width 150 cm. Excavated soil shall not be piled on the edge of the ditch, and the ridge surface shall be slightly arched back to avoid ponding. General grass and rice stubble do not affect planting, if there is large grass can be trampled down or hoe, do not use herbicides. Sow 4 rows per ridge, planting in wide and narrow rows, with wide rows in the middle, row spacing 34 cm, narrow row spacing 28 cm on both sides, plant spacing 25 cm, and 20 cm on each ridge. According to the "pin" shape, about 6000 plants are planted per mu. Place the seed potato on the soil surface (preferably pressed into the mud), the bud eye close to the soil surface, and then evenly cover the straw 8~10 cm thick (the so-called 8~10 cm is not the thickness of the straw after compaction, but "gently patted, pressed but not solid"). Straw should be spread over the entire surface of the bed, leaving no empty space. Otherwise, the heat preservation and moisture retention effect will be reduced, the potato pieces will be easy to appear green, the green potato rate will be high, and the commodity rate and commodity quality will decrease.
2. Buried seeds covered with straw
The other method is the same as the previous one, except that the seed potatoes are buried in the soil by digging holes and burying seeds or covering seeds with trench soil.
3. Buried seeds or directly planted, covered with straw and then covered with soil
No-tillage rice field, plow high-yield ditch (irrigation ditch) in advance, ditch width 30 cm, depth 20 cm, ridge width (wrapped ditch) 100 cm (large ridge inconvenient to cover soil), ditch soil reserved for straw cover. Sow 2 rows in each plot, bury seeds in double rows in the shape of "pin" according to the specification of row spacing of 0.30 meters and plant spacing of 0.25 meters, and plant about 5000 plants per mu. Then evenly cover with straw about 5 cm thick. Then dig a high-yield ditch (irrigation ditch), and the excavated soil is directly covered on the straw, with a thickness of 5~8 cm. characterized by simultaneously having all the advantages of constant tillage and no-tillage straw mulching cultivation, avoiding the deficiency that no-tillage straw mulching cultivation cannot be carried out due to insufficient straw, and greatly reducing the green potato rate.

Cultivation techniques of Potato covered with Straw
The first is to choose a place to rectify the bed. Choose neutral or slightly acidic rice fields. It is better to leave a stake of 15cm to 20cm during rice harvest. Before sowing, delimit the border and open the ditch, with a width of 1.4 to 1.6 meters, a width of 20 to 30 centimeters and a depth of 15 to 20 centimeters. The soil dug up during the trench should be thrown evenly in the middle of the border, and the surface of the border should be arched to facilitate drainage. The second is seed potato treatment. Choose virus-free potato species with no disease and insect pests, smooth and fresh skin and a single weight of more than 20 grams. Before sowing, according to the distribution of bud eyes of tuber and potato

High-yielding cultivation techniques of Potato with Rice Straw
The main results are as follows: 1. fresh potato varieties are selected, such as Zihua 851, Zhongshu 3, Fewurita and so on. 2. Soil preparation and soil selection: potato adapts to a wide range of soil, and both sand and soil can be cultivated. But choose loose soil, good drainage, PH5.5-6.5 slightly acidic sandy soil. Potato belongs to Solanaceae, so it is not allowed to be cropped continuously or centrally mixed with other Solanaceae crops. Small high ridge soil preparation: after the previous harvest, break the soil with a rotary tiller, and then use a border preparation machine to press the width of the furrow 110-
