Problems solved by technology

For this reason, in the process of yam cultivation, growers need to pay attention to the precautions of yam planting, implement comprehensive control strategies, and enhance the application of green control technologies, and cooperate with other effective control methods to control pesticide residues in yams. At the same time, strengthen its control effect; the current method for the prevention and control of yam pests and diseases is mainly to spray pesticides, which will cause a large amount of pesticide residues and reduce the safety of yams

Abstract

The invention discloses a method for preventing and controlling diseases and insect pests in yam planting, which comprises the following steps: applying a slow-release fertilizer to the planting soil, and spraying a dilution of a microcapsule insecticide into the planting hole; the slow-release fertilizer Composite fertilizer granules composed of urea, potassium dihydrogen phosphate, and calcium nitrate are used as the core, konjac glucosidan modified acrylic acid-acrylamide copolymer is used as the inner coating material, and nano-montmorillonite is used as the outer coating material ; Spray foliage fertilizer after the upper half of the yam vines; the foliage fertilizer includes humic acid, sodium alginate oligosaccharides, oligogalacturonic acid, urea, deionized water and graphene; in early June to In the second ten days of July, the dilution of the microcapsule insecticide was irrigated in the field; the microcapsule insecticide used phoxim as the core material and the β-cyclodextrin/soybean soluble polysaccharide compound as the wall material. The method can effectively reduce the pests and diseases in the yam planting, improve the quality of the yam, have less pesticide residue on the surface of the yam, and have high safety.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for preventing and controlling diseases and insect pests in yam planting. Background technique [0002] Yam, also known as yam, yam, is a plant of the Dioscoreaceae family and the genus Dioscorea. Like most Dioscorea plants, the underground tubers of yams are edible. The leaves of yam are different due to different species, with alternate, opposite, single leaves or 3-7 finger-shaped leaflets, and there are pearl buds in the leaf axils. The flowers of yam are unisexual flowers, which belong to dioecious plants, and the inflorescences are arranged in spikes or cones. The number of stamens is not the same, some 6, some 3: ovary 3 chambers, 2 ovules in each chamber. The fruit of yam is a capsule, the fruit and seeds have wings, and the fruit has three wings. Chinese yam is widely distributed in Northeast my country, North China, Central China, Southeast China and So...
