Today, Huinong.com is mainly about the prevention and control technology and application of the root-knot nematode in the facility. It is analyzed in the case of Helan County in China. In the past two years, the disease was in Yinhe Village and Hanzuo Village, Jingui Town, Helan County. The degree of occurrence is biased and spreads. In particular, melons and eggplants are the most seriously damaged, which has seriously affected their production and planting. 1 The harm of melon root knot nematode The root-knot nematode has a wide range of hosts. After the disease occurs, it will generally reduce production by 10% to 20%, and severely by more than 75%. The damage of nematodes to vegetables is not only in itself, but also in interaction with other diseases. Can aggravate the occurrence of diseases. The prevention and control of melon root-knot nematodes is a new topic facing the agricultural production of Helan County. It is a new problem facing the agricultural production of facilities in the economic and effective prevention and control of such pests and diseases in the facility agricultural park. Causes of root knot nematodes The occurrence of root-knot nematodes is mainly due to the continuous cropping of vegetables, the loss of seedlings, the use of agricultural machinery, and the operation of farming, especially with the use of factory-made commercial seedlings, and the use of seedlings containing eggs in Shandong and other places. The sheds and the long-planting sheds provide a suitable environment for the growth and development of root-knot nematodes, so that root-knot nematodes in the soil can accumulate and multiply. 3 root knot nematode control measures 3.1 Physical control It is strictly forbidden to plant seedlings and organic fertilizers in the affected areas to prevent the spread of root-knot nematodes with seedlings. Clean the pastoral, completely burn the diseased plant residue, cultivate disease-free seedling transplanting, and avoid secondary infection. Rotation of onion and garlic, Meloidogyne host by a wide range, with the required rotation Bulb 2 to 3 years will have effect. 3.2 Treatment of nematode hazard shelters 3.2.1 The use of calcium cyanamide (Ningxia Darong chemical production, "Rong Bao") combined with high temperature stuffy studio prevention of root-knot nematode 6 year - August greenhouse hot season of leisure, with 50% of calcium cyanamide and straw (wheat straw, rice straw, corn stalks and the like crushed into segments of 4 ~ 6cm) or decomposition of organic fertilizer applied to the soil ridge tillage , covering film irrigation, Greenhouse closed for disinfection. The specific operation method is to shed the ground floor, apply the broken straw + calcium cyanamide, and mix well with the soil, use the rotary tiller to rotate the ploughing 2 times, then ridge, ridge width 60cm, height 40cm, and cover the mulch or film (It is best to use a new membrane). The membrane is filled with water and the chamber is sealed. The tighter the seal, the better. The surface temperature during the day can reach above 60 °C. When the temperature of 20cm soil layer is above 45°C for more than 15d, it can kill root-knot nematodes, disinfect soil and reduce soil salinity. It implements a greenhouse with high-temperature shacks and kills beneficial microorganisms. When planting vegetables, consider applying a certain amount of biological fungicide. 3.2.2 Using ridge Xin soil fumigation Clear previous crop stubble and weeds, deep plowing soil 25cm, leveling rake thin, uniform and fine soil particles. Watering according to the soil moisture, the soil water content can reach 60%~70%, that is, the degree of hand-kneading into the group, landing and dispersing, keep 3~4d, evenly use the ridge Xin 98% micro-particle agent 20kg/667m, the pests and diseases are serious It is recommended to apply high doses on the plots, and apply low doses on plots with light pests and diseases. Pay attention to the soil layers such as columns and ditch edges. Do not miss the soil immediately after application. Deeply turn the soil 20cm to mix the chemicals with the soil. Or thick plate to properly flatten the soil to ensure that the agent is in full contact with the soil; after pouring an appropriate amount of water, use a plastic film to compact the area around the application area to prevent air leakage. After the closed disinfection, remove the film and loosen the soil above the 20cm soil layer. 1 to 2 times, i.e. administration vent dig deeper than the depth, permeability of about 1Od, the residual gas is full. 3.2.3 using Fuqi multi-soil disinfection 10% thiazophos granules (rich blessing) can hinder the activity of nematodes and gradually reach the nematocidal effect. It can prevent the nematode from invading the roots of plants, prevent the production of larvae in the oocysts, prevent spawning, stabilize the effect, and have high effect. There is almost no requirement for soil quality, pH, ground temperature and other conditions. It has an infiltration effect in plants, and can prevent and control thrips and aphids, and does not affect soil microorganisms, and is safe for humans and animals. The method of operation is that the dosage of 10% thiazolyl granules is 4kg/667m, and the agent and the fine sand are first mixed in a ratio of 1:20, and then the half agent is evenly applied to the soil surface, and the cultivating is 20~30cm, flat, and then Open the planting ditch, sprinkle the other half of the agent into the planting ditch and mix with the soil. The above is the whole content that Huinong.com has brought to everyone. In the past two years, the roots of plants damaged by nematodes have poor growth, do not grow capillary roots, and serious nematodes such as loofah can make the soil arch. After the nematode damage occurs in the roots, the water and nutrients are basically no longer absorbed, and the plants are prone to wilting, and severe cases will result in production. To learn from and introduce existing domestic and foreign root-knot nematode control technologies, and to effectively improve and integrate, to reduce the occurrence of root-knot nematodes, improve crop yield, improve crop quality, and form a technical system to effectively control and control greenhouse root-knot nematodes. Provide technical support for promoting sustainable production of the facility vegetable industry. Through experiments, the relative control effect of root-knot nematodes in the demonstration area exceeded 75%, and the yield increased by more than 30%.
