Melon cultivation experience
Since last year's popularization of the use of bioactive fertilizer for planting black melons in Sanshui City (district), not only is there a significant fertilizer effect, but the most prominent is its function of preventing disease and preventing dead seedlings, so that the farmers' melon seedlings are full-grown. , high yield and quality. This year, we also performed fertilization demonstrations on the 6 acres of early-stage melons produced by farmers in Chenshao and Ye Shaolian, Dabusha Village, Datang Town, Sanshui District. According to Chen Yu, the use of several sunflower seed fertilizers, combined with farm manure and a small amount of chemical fertilizers, saves 30% more money than the old one. With careful field management, melons thrive and have fewer pests and diseases. The survival rate is as high as 98%, and it is expected that they can be sold at a good price. Now, Chen Yu’s early management of fertilization management for wax gourd is summarized. 1, base fertilizer. Mu with 1000 pounds of farmyard manure (large dung) plus 100 ~ 150 kg of sunflower seed eco-fertilizer, mixed piled up 15 days, ditch applied. At the time of application, 25 kg of compound fertilizer with a content of 25-30% was added. 2, the first top dressing. 7 days after planting, the Mu with sunflower seed ecological fertilizer 5 ~ 8 kg, urea 1 ~ 2 kg, and some farmhouse manure water co-immersed for 24 hours after application. 3, the second top dressing. Seedling period of 8 to 10 leaves, acres of ecological fertilizer 8 to 10 kg of urea 2 to 5 pounds, it is best mixed with fecal water manure after 24 hours. 4, the third top dressing. Melon seedlings have 12 to 15 leaves, 15 to 20 pounds of eco-fertilizer, 5 pounds of urea, and some farmhouse manure in total for 24 hours. 5, melon vines after the top dressing. Mushi ecological fertilizer 20 ~ 30 kg, compound fertilizer 5 kg, plus sunflower seed LPK fertilizer 3 kg, a total of 24 hours after soaking. In the second half of the year, we must use LPK fertilizer to dip water once more, depending on whether or not to add other fertilizers to look at the growing trend. In short, we must provide sufficient nutrition for long melons. 6, strong tail fat. According to the growth condition of the farmers, the main use is to use the green sunflower seedlings or some other foliar fertilizers. Spray once in a week or two, dilute 500 to 1000 times, and spray with non-alkaline pesticides. . Frequent spraying of leaf fertilizers with various trace elements is very important to maintain balanced nutrition. Although the early stage seedlings are kept well, they must not be taken lightly in the middle and later stages. Otherwise, the mortality rate of melon seedlings is often above 50%. This situation often occurs in production, causing melon farmers to suffer heavy losses. Demonstration field According to the above fertilization scheme, the rate of dead plants in the melon field can be controlled within 5%. (Sanshui) Datang Hengli Agribusiness Cao Yuanshen 〗 〖Postscript in May 2003 On May 13, Jinkui Subsidiary sent experts to investigate. Melon spacing (畦1.8 meters, ditch 0.5 meters) 2.3 meters planted a single row, the average spacing between plants 0.58 meters, the number of theoretical acres of 500 strains, the actual number of 475 strains. Melon vines are very prosperous, with large leaves and no spots. Only one dead plant, one mosaic disease, and two to three suspected mosaic disease plants were found in the field. Numerous fruits, large have 6 ~ 8 kg, more than 10 days can be listed one after another, is really rare good melon. Chen Xi and Ye Shaolian's experience in fertilization is that the base fertilizer and multiple top dressings are all applied with the kumquat eco-fertilizer, and they are used together with farmyard manure (leaching) to increase the proliferation of beneficial microorganisms, improve the fertilizer efficiency of farmhouses, and inhibit the disease. Two applications of LPK fertilizer for growth and development of melons (the amount of which may be more) were applied twice after the upper shelf, and foliar spraying of chlorophylla etc. was paid attention to maintain balanced nutrition at the seedling stage and middle and late stages. Of course, through comprehensive measures to prevent and reduce disease, the first is to implement crop rotation (before the field as horseshoe), apply active biological fertilizers for disease prevention and fertigation, use high-efficiency and low-toxic pesticides to prevent and treat pests, and implement meticulous management to achieve ideals. The economic benefits. Chaenomeles is a variant of wax gourd, both of which require similar fertilizers and management. The above-mentioned experience of Sanshui Datang is only for the reference of farmers and farmers who plant melon and zucchini everywhere.
