Embodiment 1

[0030] Water conservation in the paddy field needs to protect the field at the bottom of the plow. The middle rice stubble autumn potato high-border deep furrow straw mulch farming method takes the following steps.

[0031] A) Making borders. After the mid-season rice is harvested in the first ten days of September, the stubble slab field is set out to make a border. The border is 90cm wide, and the border is 50cm wide. A border is ploughed on both sides, and the soil block is 20cm wide and 13cm thick. Plow neatly on the borders to form a 13cm high soil ridge, leaving a 10cm stubble in the center of the border.

[0032] B) Base fertilizer, compound fertilizer and farmyard fertilizer are spread on the border slab field.

[0033] C) Sowing, seed potatoes are planted on the border slab field, 2 rows per border, the spacing between the border rows is 45×20cm, the spacing between rows is 95×20cm, the average row spacing is 70×20cm, and 4761 holes are sown per mu.

[0034] D) Cover the gras...

Embodiment 2

[0038] The mid-rice stubble of keeping small potatoes as seed potatoes, the autumn potato high-border deep furrow straw mulching farming method, take the following steps.

[0039] A) Making borders. After the mid-season rice is harvested around the beginning of September, the stubble slab field is set out to make borders. The border is 100cm wide, the border 40cm wide, a border is ploughed on both sides, the soil block is 20cm wide and 13cm thick. Plowing neatly on the borders of the border, forming a 13cm high soil ridge.

[0040] B) Base fertilizer, compound fertilizer and farmyard fertilizer are spread on the border slab field.

[0041] C) Sowing, the seed potatoes with small potato pieces are usually nearly half the size of the standard seed potatoes, so the seeding density should be increased. Two rows are sown per border, the spacing between the border rows is 50×13cm, the spacing between rows is 90×13cm, the average row spacing is 70×13cm, and 7325 holes are sown per mu.

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...
