Technical guidelines for fertilization in the whole process of planting ginger
Ginger should be fully fertilized before planting. 2030 piculs of rotten cow dung and 200 kilograms of plant ash can be applied per mu, and mixed with soil after application. After ginger sprouts, it is necessary to weed and loosen the soil in time. Because of the large amount of fertilizer needed in the growth process of ginger, it should be spread many times. Generally, about 10 days after the full seedling, the height of the seedling is 2 to 3 inches, and 20 kilograms of sparse human and animal manure, 15 kilograms of potassium chloride or potassium sulfate should be applied per mu. When ginger grows to 7-8 leaves, 20-30 tons of pig and cow manure are used per mu, or rotten soil manure is used as promoting fertilizer. After application, cover the border with soil to keep the soil moist, and combine with ploughing and weeding to cultivate soil. The human feces, urine or cake fertilizer used must be fully cooked. Ginger is a potash-loving crop, which is sensitive to the effect of potash fertilizer, so it is necessary to apply more organic fertilizer and more available potash fertilizer. For high-yielding ginger, it is also required to apply half a jin of phosphorus and potash fertilizer per hundred holes after the seedling grows to 1 foot. After 40 days, 2 jin of ammonium bicarbonate was applied. From July to August, the ginger lump should be ploughed and weeded for 2 or 3 times a month, and the seedlings should be fertilized and the soil should be added frequently to prevent the rhizome from being exposed and affect the quality. To the Beginning of Autumn, it is necessary to cultivate the soil, combined with the application of one and a half jin of urea. The End of Heat applied ginger fertilizer again before and after.
