In order to be able to do more, the melon is called cassava, and it is necessary to take into account four aspects of management skills, which are more conducive to achieving a high yield of the melon. Through proper planting management, the melons can be big and many。
1. The choice of high-quality melon seedlings with high-quality, high-pregnancy and disease-resistant varieties, and the variety of good varieties of melons that are common, such as the edible variety 25, potato 32, potato 9, potato 19, sinnon 431, beijing 553, potato 87, potato 10, chest 22 and potato 34, cardio, potato 1 and many others, can be directly selected or nurtured with chips。
2. Select suitable soil, taking into account the adequacy of nutrients in the soil, the fact that the melons are less demanding to the soil and have a strong adaptive capacity, but are best suited to the depth of the soil, its perturbation and abundance of organic matter, the higher content of the potassium element and the fact that the soil is between 4. 2 and 8. 3, with good drainage and drainage conditions. Landmelons are not well grown in low-lying areas where water is readily available, as they are not normal in the event of consecutive rains. The soil has an imbalance in the ratio of potassium nitrogen phosphorus, which does not meet the growth needs of the melon, which requires rational fertilization, since the melon is an organic fertilizer that prefers potassium-rich elements. The ratio of melon demand for potassium fertilizer for nitrogen phosphorus is estimated to be approximately 2:1:4. Approximately 3. 7 kg of nitrogen, 1. 7 kg of phosphorus quintophos and 7. 5 kg of potassium oxide are required from soil per 1,000 kg of fresh melon produced. Therefore, an appropriate increase in the application of potassium fertilizer in soil contributes to an increase in the production of melons, especially during periods of expansion of the melon
3 the method of planting melons in the ground, which are able to survive with chicken tungsten plugs, and the lack of soil moisture at the time of planting, can affect potatoes. The seedlings take root and pour around a kilogram of water per week, which is then covered with soft soil. In general, seedlings of red potatoes can be planted on a flat, tilted or standing basis, and must be buried in at least two knots in order to facilitate the production of roots。
4 the emphasis on field management, with many projects in the field of melon management, combines the plowing of pine soil with weeding, both to ensure that the soil is abated, to preserve water and to avoid competition for soil nutrients by weeds. The proper application of 10 kg of high nitrogen-high potassium compound fat, especially in the weaker ground seedlings, is expected to take place about a month after the transfer of the melon seedling. Potassium migration for about three months, with a significant increase in the demand for potassium elements, should be supplemented with targeted additional potassium sulphate ten kilograms of land per acre to facilitate the expansion of the nutrients needed for root expansion, with attention to the use of crack fertilizer。
In field management, there is also continuous top-to-top control or spraying of plant growth regulators to control the growth rate of chickens and to avoid uncertainty of root by lifting chickens or flipping. It is also a method of supplementing nutrients through folic fertilizers, commonly used as potassium dihydrophosphate, plant growth regulators, and various trace elemental foliage. Spraying every 10 to 15 days during the magnifying period of the sweet potatoes contributes to the expansion of the red chips. All right, that's all the sharing of this chapter is here. We're here, we're here, we're here. Learn more of the technical experience and techniques of growing sweet potatoes and welcome the relevant columns。
