A plant protection method for improving the yield of potato virus-free original seeds

Abstract

The invention discloses a plant protection method for increasing yield of virus-free potato breeder's stock. The method comprises the steps: (1) constructing production facilities; (2) carrying out environment disinfection; (3) carrying out matrix preparation and pretreatment; (4) carrying out tissue culture seedlings grading and root dipping treatment; (5) carrying out cuttage transplanting; (6) carrying out field management; (7) carrying out water management; (8) carrying out seedling pressing management; (9) carrying out fertilizer application management; and (10) carrying out harvesting and sorting. According to the method, a nutritional rooting agent, which is prepared through mixing 1.25g of Tradecorp, 7.5ml of Feifan, 30g of ANIRAM, 30g of lizhi and 15L of clean water, is used for carrying out root dipping treatment on tissue culture seedlings, optimal water management is implemented according to different requirements of the tissue culture seedlings on moisture at a seedling recovering stage, a potato tuber expanding stage, a small potato harvesting stage and a creeping stem forming stage, and liquid nutritional fertilizers for different growth needs are applied in an irrigation manner after the tissue culture seedlings are planted, so that the reasonable control on growth, sterilization and bacteriostasis is promoted, and the aims of increasing yield and improving quality are achieved.

Description

technical field [0001] The invention belongs to the technical field of potato original seed cultivation, and in particular relates to a plant protection method for improving the yield of potato virus-free original seed. Background technique [0002] Potato is the fourth largest crop in the world after wheat, corn and rice. It is not only rich in vitamin B1, B2, B6 and pantothenic acid and other B vitamins and a large amount of high-quality cellulose, but also contains trace elements, amino acids, protein, fat and High-quality starch and other nutrients are the most affordable anti-aging food. my country is the largest potato producer in the world, accounting for 1 / 4 of the global potato planting area. According to statistics, my country's potato planting area is about 80 million mu, but unscientific planting methods lead to low yield, poor quality, and low income, which seriously hinders the development of the potato industry. [0003] In recent years, with the rapid devel...

Problems solved by technology

[0004] The object of the present invention is to: overcome the above problems of high cost, poor sterilization and disinfection effects, difficult control of rooting agent dosage and rough fertilization after planting, and provide a plant protection method for improving the yield of potato detoxified original seeds. The rooting agent is used for root dipping treatment, combined with the disinfection nutrient solution for fertilization management, in order to achieve the purpose of promoting the growth of tissue culture seedlings, swelling of stems, and improving yield and quality
