Embodiment
[0019] Choose early-maturing potato varieties, such as "Dongnong 303" and so on. After the harvest of single cropping rice or continuous cropping late rice in the same year, it can be sown in the middle and late February of the second year when the temperature is suitable. Since straw mulching can properly increase the soil surface temperature, the best sowing time can be brought forward to the end of January. Potatoes are generally grown in paddy fields.
[0020] Potatoes have a short growth period, require a large amount of fertilizer, and are sensitive to phosphorus and potassium fertilizers. All fertilizers are used as base fertilizers. Generally, 3,000 kilograms of organic fertilizers are widely spread per mu, and 40 kilograms of ternary compound fertilizers are applied before ditching. It is best to fertilize strips and apply them between seed potatoes. Before the potatoes are sown, the furrow is 1.2 meters wide, the ditch is 30 cm wide and 20 cm deep, and the soil in ...

Abstract
The invention discloses a paddy field tillage-free planting device for covering sliced potatoes with straws. The method comprises the following steps of: from the harvest of annual single-season rice or continuous cropping late rice to the middle and late ten days of February of the next year, slicing seed potatoes, ensuring that each slice must contain eyes, mixing plant ash and the seed potatoes, planting the seed potatoes in the soil in a mode that the sliced surfaces of the seed potatoes are upward, namely the eyes are planted towards the soil, and uniformly covering the straws on the planted seed potatoes, wherein the straws are spread on the whole ridge surface. The potato buds on the sliced surfaces of the seed potatoes face the soil so that the potato buds and the grown potato roots are directly contacted with the soil, proper temperature and humidity conditions are provided for the growth of the potatoes, the germination speed of the potato buds is quickened and the seedling forming rate is improved. The method is also suitable for planting the potatoes in dry lands in a tillage-free mode.
Description
technical field [0001] The invention relates to a potato planting method, in particular to a no-tillage rice straw-covered potato cutting planting method in a paddy field. Background technique [0002] The traditional potato planting methods use plowing, ditching, soil preparation, furrowing, planting, fertilization, and soil covering, etc., which require a lot of work and low work efficiency. During potato harvesting, there is a lot of soil on the surface of potatoes, and they are often broken, which affects the commodity rate of potatoes. No-tillage paddy fields and straw-covered potatoes are planted. After the rice is harvested, when the potatoes are planted, in the no-tillage field of the paddy field, ditch to make a border, fertilize, put the cut potato directly on the border surface, cover with straw, and With appropriate cultivation measures, a higher yield of fresh potatoes can be obtained, and the three labor-intensive processes of plowing, soil preparation, and fur...
