Embodiment Construction

[0012] First of all, select excellent species. This embodiment selects Jinshu No. 11 seed potato, the depth of cultivated land is 25cm, the planting depth of seed potato is 15cm, the planting time is late March, and the planting density is 3200 plants per mu. On the basis of farmyard manure, apply 50 kg of compound fertilizer and 20 kg of urea, and spread evenly. When sowing, 0.5 kg of zinc mixed with phosphorus per mu is sprinkled around the seed potatoes to prevent underground pests. In the middle of the month, spray metalaxyl 2-3 times to prevent and control late blight. In the budding stage, before the roots are needled, the soil is cultivated.

Abstract

The invention discloses a high-yield cultivation technique for detoxicated potatoes. The technique is to increase the yield of detoxicated potatoes by more than 500 kilomgrams by accelerating germination and drying seeds in advance, reasonable potato seed planting depth and density, and reasonable management of fertilization, pest control, molding, etc.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a high-yield cultivation technique for virus-free potatoes. Background technique [0002] Potato has a short growth period and high yield. It is a food, vegetable and feed crop. It is not only rich in nutrition, but also has the characteristics of easy storage and transportation. It has great potential for market development. Virus-free potatoes have the advantages of no virus infection, early tuber formation, fast expansion, high yield, and good quality. In recent years, virus-free potatoes have been gradually promoted throughout the country, but the yield is generally unsatisfactory. Contents of the invention [0003] The purpose of the invention is to provide a high-yield cultivation technique for solving the low yield of virus-free potatoes. [0004] The technical scheme adopted in the present invention is: a kind of high-yield cultivation technology of virus-free p...
