Melon cultivation and disease prevention strategies


There are many diseases in melon cultivation, such as wilt disease, disease, anthrax and so on. Based on many years of production experience, the author believes that vegetable farmers should start with the etiology and adopt comprehensive measures to maximize control and reduce the occurrence of diseases.

First, implement crop rotation to control soil spread

Implementation of rotation, better disease prevention. Farmers on the scale of vegetable crops should divide the vegetable field into 3-5 districts and implement the zoning rotation. With a small area, we must divide the field into two areas and plant melons every other year. It is advisable to plant rice or aquatic crops for a year or to grow crops such as onions and garlic that can excrete bactericidal substances in places where conditions are favorable during rotation, and to avoid planting crops that are similar to melons. If seedlings are transplanted and transplanted, nursery plots should use fields that have not been planted for melons for many years, and bagging seedlings should use loam that has no melons. Should also pay attention to clean up the melon field, focus on the burning of diseased plant residues. If you use guatuga glutinous rice, it is best to use high-temperature stacking to kill germs; Aphids are communicators of viral diseases. Crops that are prone to aphids should be avoided beside melon fields.

Second, improve fertilizer technology, pay attention to organic fertilizer

The use of a mixture of bio-fertilizer and conventional fertilizer after dipping (leaching) can not only increase fertilizer efficiency, but also increase the effective nutrients in the soil through the proliferation of beneficial microorganisms, greatly increasing the proportion of beneficial micro-organisms in the rhizosphere, thereby enhancing the antagonism of pathogens. Suppresses its pathogenicity. Through years of demonstration and promotion in vegetables and fruit trees, Guomanduo Bioorganic Fertilizer and Kokaxi Bio-organic Fertilizer are used together with farmyard manure as base fertilizer, and dip-dip with urine manure for multiple fertilizers (with partial application of fertilizer). The fertilizer effect is good, the wilt disease at the seedling stage and the adult plant, and the incidence of the disease can be significantly reduced (taking the round as a precondition, with chemical prevention and control).

In addition to eco-fertilizers, high-quality compound fertilizers can provide N, P, and K necessary for wax gourd, combining the long-term efficiency of organic fertilizers with the quick effects of chemical fertilizers. The critical period of winter melon P and K nutrition is at the seedling stage, so the base fertilizer must contain enough phosphorus and potassium. The domestically produced Yangfeng compound fertilizer and the Japanese resident compound compound fertilizer have been used for many years to demonstrate a clear effect on the harvest of high yield of crops. In particular, the commercial compound fertilizer has both quick-acting and long-lasting functions, and has a high fertilizer utilization rate.

A lot of dead seedlings in the early days of the Guaranta were not much, but after the vines spread on the sheds (shelfs), the dead plants suddenly increased, even reaching more than 50%. The reason is that it is related to improper application of nitrogen fertilizer under high temperature and rain conditions. The experience that has been summed up is: Do not apply before heavy rain, and do not apply immediately after the rain; Partial application of concentrated nitrogen fertilizer can easily cause blight and disease. For peracid soils, applying lime to neutralize the acidity of the soil can help improve disease resistance.

Wax gourd needs large amount of fertilizer, and the demand for potassium in the three elements is the largest. After the flowering results, on the basis of high-quality compound fertilizers such as high-quality Yangfeng and dwellers, foliar spray of high-potassium, proline, and other high-potassium foliar fertilizers for 2-3 times can effectively supplement the lack of root absorption and provide melons. Need a variety of trace elements.

Third, sorghum drainage, selection of disease-resistant varieties

The melon plants grow vigorously, the leaves are large, the melons are large and high-yield, and the consumption of nutrients and moisture are all more. However, wax gourd and zucchini are not tolerant to leaching, and oversaturated roots of melon fields in rainy season can cause various diseases. Building sorghum to ensure that drainage is unblocked is an essential factor for high quality and high yield; ensuring uniform pouring (leaching) of water during squashing is also important for the normal growth of melons. When wet when dry, melon shape is not correct, poor quality or even stop development.
