High-yield cultivation method for potato high-ridge close planting

Abstract

The invention discloses a high-yield cultivation method for potato high-ridge close planting. The method includes the following steps that firstly, a sandy planting field is selected, deep scarification and ridging are conducted, ditches are communicated with each other, and the furrow ditch is deeper than other ditches; secondly, 500-750 kg of composted chicken manure or 300-500 kg of organic composite fertilizer with the composted chicken manure as the raw material, 75 kg of long-acting controlled-released composite fertilizer, 40-45 kg of quick-acting composite fertilizer, 2.5 kg of magnesium sulfate and 1 kg of zinc sulfate and agricultural borax are applied to each mu of planting field, and soil covering is conducted after the fertilizers are applied to the ditches in furrows; thirdly, seed potatoes are purchased and diced, wherein each potato dice is 30-50 g heavy, and 1-2 holes are formed in each dice; fourthly, the seed potatoes are sown from the late October to late November at the temperature of 17-21 DEG C, and 4000-5000 plants are sown in each mu; fifthly, soil is watered and wetted 4-7 days after sowing, the soil is irrigated with a proper amount of water according to actual conditions in the seedling period, accumulated water is drained 20 days before harvesting, and the situations that rotten potatoes are caused due to accumulated water and ditches need to be drained when the amount rainwater is excessively large are prevented; sixthly, when stems and leaves of potatoes become yellow and after potato skin is lignified, the potatoes can be harvested. The method increases the potato yield.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a high-yield cultivation method for high-ridge and close-planting potatoes. Background technique [0002] Potato (scientific name: Solanum tuberosum L.), a perennial herb belonging to the Solanaceae family, with edible tubers, is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also called ground eggs, potatoes, potatos, etc., the tubers of Solanaceae plants. Together with wheat, rice, corn, and sorghum, it has become the world's top five crops. [0003] The output of traditional potato planting technology planted is about 3000 kilograms per mu, and the potatoes planted with existing planting methods are difficult to make breakthroughs in yield due to reasons such as plant diseases and insect pests; A lot of research and promotion, but still not ideal. Contents of the invention [0004] The object of the present inve...
