A water-fertilizer-medicine integrated cultivation method for improving disease resistance of winter-planted potatoes

Abstract

The invention relates to the technical field of winter potato planting, in particular to an integrated cultivation method of water, fertilizers and medicine for improving disease resistance of winterpotatoes. The method comprises the steps of soil preparation, germination, seed cutting, planting, drip irrigation and the like, in the step of soil preparation, and organic fertilizer stack retting is conducted in advance to make the soil fertility stronger and more loose, which can meet the needs of the potatoes to promote tuber expansion and root growth during the growth; during the germinationand seed cutting process, an inventor germinates in advance, cuts buds and disinfects to improve the growth and resistance of the potatoes; drip irrigation is conducted, water and fertilizer management in the later stage of the potatoes can effectively combine water, liquid fertilizers and biological pesticides, pests and diseases are prevented and controlled while fertilizers are applied, pesticide dosage is saved, labor costs are also saved, meanwhile the use of the organic fertilizers and the biological pesticides does not cause pesticide residues, and the method is a safe, effective and efficient integrated management method of the water, the fertilizers and the medicine for the potatoes.

Description

【Technical field】 [0001] The invention relates to the technical field of planting winter potatoes, in particular to an integrated water, fertilizer and medicine cultivation method for improving the disease resistance of winter potatoes. 【Background technique】 [0002] Potato (scientific name: Solanum tuberosum), Solanaceae Solanum, annual herb, also known as potato, ground egg, yam, etc. Potato is one of the important economic crops in southern my country. Potato is propagated by tubers and rich in vitamin C. It is a healthy and popular staple food crop. Erosion, resulting in a high rate of insect eyes, the organisms that cause damage to potatoes include aphids, cutworms, needleworms, cutworms, mole crickets, grubs, late blight, viral diseases, ring rot, bacterial wilt, scab, etc. Among them, aphids are the most Likes to erode the leaves of potatoes, which will lead to the reduction of potato production, and the potato pieces will be sunken, not plump and irregular due to abn...

Potato is one of the important economic crops in southern my country. Potato is propagated by tubers and rich in vitamin C. It is a healthy and popular staple food crop. Erosion, resulting in a high rate of insect eyes, the organisms that cause damage to potatoes include aphids, cutworms, needleworms, cutworms, mole crickets, grubs, late blight, viral diseases, ring rot, bacterial wilt, scab, etc. Among them, aphids are the most Likes to erode the leaves of potatoes, which will lead to the reduction of potato production, and the potato pieces will be sunken, not full, irregular due to abnormal photosynthesis, which will affect the quality of potato pieces. At present, in the cultivation of ordinary potatoes, insecticides are highly toxic and have The 3911 with systemic effect can be used for seed dressing or soaking to effectively control above-ground and underground pests, or to apply pesticides by spraying. Technical defect of large amount of pesticide residues
