Embodiment 1

[0034] The rice stubble spring potato expansion ditches backed up soil straw screen anti-frost cultivation method of soil living mud field block, take the following steps.

[0035] A) Ditch digging. After the autumn harvest, dig a field-shaped or well-shaped ditch in the live mud field, dredge the drainage ditch outside the field, reduce the water level in the field, and make the paddy field dry and suitable for farming.

[0036] B) To make a furrow, the width of the furrow is 100cm, and the width of the furrow is 40cm. Plow on both sides of a furrow. The soil block from the furrow is 20cm wide and 13cm thick.

[0037] C) Deep furrows, deep furrows in time after making furrows, hoe the furrows to 25cm below the field surface, and move the soil blocks in the furrows at the same time, stack them into 30cm wide soil ridges, and form two 15cm wide soil ridges with the edge of the furrow , 13cm deep seeding ditch.

[0038] D) Base fertilizer: Before the potatoes are sown, apply th...

Embodiment 2

[0046] The following steps are taken for the cultivation method of rice stubble and spring potatoes with topdressing farm miscellaneous fertilizers to expand ditches and back up soil curtains to prevent frost.

[0047] A) Make furrows, from mid-to-late November to early-to-mid-December after the end of autumn harvest and autumn planting, stake out ditches to make furrows on the rice stubble fields. The furrow surface is 100cm wide, and the furrow width is 40cm. Both sides of a furrow are plowed. The soil block from the furrow is 20cm wide and 13cm thick. Plow neatly on the edge of the furrow to form a 13cm high soil ridge.

[0048] B) Deep furrows, deep furrows in time after making furrows, hoe the furrows deep to 25cm below the field surface, move the soil blocks in the furrows at the same time, stack them into 30cm wide soil ridges, and form two 15cm wide soil ridges with the edge of the furrow , 13cm deep seeding ditch.

[0049] C) Base fertilizer: Before the potatoes are ...

Abstract

The invention discloses a rice stubble spring potato groove-expanding soil-hilling anti-frost cultivation method. The method includes: A), ridging, wherein a ridge face is 100cm in width, and a ridge furrow is 40cm in width; B), deepening a groove, namely timely deepening the groove after ridging, hoeing the ridge groove to be 25cm below a land face, carrying soil blocks into a ridge to form a soil ridge 30cm in width, and forming two seeding furrows 15cm in width and 13cm in depth together with a ridge-edge soil ridge; C), applying base fertilizer; D), seeding, namely seeding two rows for each ridge, wherein row spacing is 50cm, and plant spacing is 26cm; E), earthing, namely clearing the ridge furrow, leveling the ridge face and earthing to cover potato seedlings; F), filming, namely timely filming after seeding and earthing; G), preventing freezing; H), hilling, namely performing groove expanding and soil hilling when seedling height is about 20cm, wherein hilling elevation is 16-18cm higher than a land face; I), managing. By the method, full-land ploughing and caving are omitted, intertillage weeding times are reduced, seedling emergence time can be earlier about half a mouth due to covering a plastic film after seeding, the plastic film is uncovered after seedling emergence to cultivate strong seedlings through solarization and night exposure, and frost is prevented by covering a heat insulating material at the lowest temperature of 3 DEG C, so that stable and high yield of spring potatoes cultivated in rice stubble winter fallow land is realized.

Description

technical field [0001] The invention relates to a cultivation method for potatoes, in particular to a cultivation method for planting spring potatoes by expanding ditches and choking soil in winter slack fields with rice stubble to prevent frost in southern China. Background technique [0002] After the autumn rice harvest in southern my country, the area of ​​double-cropping rice in autumn is less, and the area of ​​winter fallow is more. There are also certain areas of winter fallow in the middle rice region and late rice region of the double cropping system of rice and wheat (oil). The winter fallow field can be developed and utilized for planting spring potatoes , which is equivalent to the sown area of ​​more than 70 million mu of potatoes in the whole year in our country. The rice stubble field in winter is a new growth point of my country's grain production. Potato is a semi-cold-resistant crop that is rich in nutrients and used as both food and vegetables. It likes co...
