Problems solved by technology

After rice harvesting in southern my country, a large number of slack fields are idle and suitable for potato planting. However, at present, potatoes are grown in slack rice fields by digging holes and planting potatoes after plowing the soil and preparing furrows. , and then cover the soil, and then use plastic film to cover the whole process or cover the soil in the early stage. The disadvantage of this method is that it needs to plow the soil, dig holes, and cover the soil. When the potatoes are harvested, the soil must be turned over, which is very labor-intensive. The soil is relatively sticky and difficult to drain, which is not suitable for the expansion of potato tubers, so the yield is low

Embodiment 1

[0008] (1) Variety selection Select Zhongshu No. 5, an early-maturing variety with a short growth period and strong adaptability; (2) Soak seeds in 500 times thiophanate-methyl solution and 20 mg / kg gibberellin mixed solution for seed potato treatment for about 18 minutes , and then cut into pieces, each piece contains 1 to 2 bud eyes, and the average weight of a single piece is about 40 grams; during the cutting process, 0.1% potassium permanganate solution is used to sterilize the knife, and the cut potato pieces are subjected to 2.5 h after air-drying, add 6% thiophanate-methyl seed dressing with plant ash; Lay flat on the furrow surface, after soil preparation, evenly spread 120 kg of cake fertilizer (7.0% nitrogen) per 667 square meters, 40 kg of potassium sulfate compound fertilizer, and 50 kg of calcium, magnesium, phosphorus and potassium fertilizer; (4) Timely sowing in mid-December For sowing, place the seed potatoes on the furrow surface with a row spacing of 33×33 ...

Embodiment 2

[0011] Dongnong 303 was selected as the seed potato; 6% carbendazim was added with plant ash to evenly dress the seeds; the rest were the same as in Example 1. The output can also reach more than 24,000 kilograms.

Abstract

A method for cultivating potato in the idle rice field in the winter includes such steps as selecting proper variety, immersing seeds, cutting blocks, drying in the air, mixing chemical with seeds, ditching, making bed, applying fertilizer, sowing in the last ten-days period of December, covering with rice straw and ground film, breaking film to leading the seedlings, applying diniconazole for suppressing the growth of seedlings preventing and treating disease and pest, and harvesting. Its advantage is high yield.

Description

technical field [0001] The invention relates to a method for planting potatoes, in particular to a method for planting potatoes in slack rice fields. Background technique [0002] Potato has strong adaptability and high yield, and is one of the four major food crops in the world. After harvesting rice in southern my country, a large number of fallow fields are idle, which is suitable for potato planting. However, at present, potatoes are grown in fallow rice fields by plowing the soil, preparing a bed, and then digging holes to sow potatoes. , and then cover the soil, and then use plastic film to cover the whole process or cover the soil in the early stage. The disadvantage of this method is that it needs to plow the soil, dig holes, and cover the soil. When the potatoes are harvested, the soil must be turned over, which is very labor-intensive. The soil is relatively sticky and difficult to drain, which is not suitable for the expansion of potato t...
