The use of wax fertilizers mainly composed of rotten farmyard manure in overwintering crops can increase the ground temperature, reduce the degree of damage to the roots of overwintering crops, and promote the growth and development of spring crops. See fertilization. Generally, the land with good fertility and sufficient base for fertilization can be applied with little or no wax fertilizer; for those with poor fertility, low base fertilizer or no base fertilizer, phosphorus and potassium fertilizers should be added; Organic fertilizer should be applied to prevent overgrowth of fertilizers to prevent the crop from growing wild after the spring is opened, causing late lodging; Sandy soil can be used in small amounts for multiple times to prevent loss of fertilizer leaching. Look at the growing crops. The application of wax fertilizer can not be “one size fits allâ€. It depends on the growth of the overwintering crops and the top-dressing of leaf color. The dark-green leaves of the leaf color are not applied with wax fertilizer; the leafy green young seedlings are less applied with wax; the yellow-green leafy seedlings are heavy. Shi wax fertilizer; especially the delayed three types of seedlings late, not only to delay the application of fertilizer, but also to speed up fertilizer, promote weak seedlings into strong seedlings, and strive to Balance production. See crop species. The application of wax must vary from crop to crop. The rapeseed will be mixed with manure and phosphate fertilizers after the maturity of Mushi 1500 to 2000 kilograms, applied to the rapeseed rows, combined with soil mulch, preferably in late December to early January next year. Among them, early maturing varieties are due to early spring and should be applied earlier than late-maturing varieties. The application of wheat wax fertilizer is basically the same as that of oilseed rape. It is advisable to use it in mid-to-late December. The application amount should be different for the seedlings. The early wheat and strong seedlings should be given as coarse and miscellaneous fertilizers, while the late wheat and weak wheat should be applied to the soil. Fertilizer mixed with quick-acting phosphate fertilizer. In general, 2500-3000 kilograms of soil and fertilizer are applied or applied per acre. See the weather fertilization. When the weather temperature is low, the slow-lasting decomposed manure, compost, pond mud, ash fertilizer, or manure urine will be used. When the temperature is higher, the chemical fertilizers such as ammonium bicarbonate, urea, and ammonium chloride that are easily decomposed will be taken over. The use of ammonium bicarbonate in crop application of fertilizer is good. Generally, 25 to 30 kilograms of rapeseeds and wheat are applied per acre, and 20 to 25 kilograms of vegetables are used for overwintering crops. According to crop types and seedlings with fertilizers. The thin and thin seedlings were mainly human fecal urine and nitrogen-based chemical fertilizers to promote seedling growth; the strong seedlings were mainly pond mud and soil miscellaneous fertilizers, and if the application of cake fats, Mushi 40 to 50 kg.
