Carrot science fertilization promotes high yield

Carrots are rich in nutrients, contain more carotene, sugar and mineral elements such as calcium, magnesium, and iron. The scientific points of fertilization help to increase the yield of carrots. At the same time in the fertilization should pay attention to the following points: 1, the application of organic fertilizer to improve quality. The supply of carrot early nutrients is mainly based on basal fertilizer, basal fertilizer should be based on pigs, chickens, cattle, horse manure and human fecal urine, 2000--2500 kilograms per acre, and sprayed with a new high-fat membrane 800 times fluid to protect fertilizer effect, to prevent germs Invade the soil; the simultaneous application of organic fertilizer must be fully decomposed, otherwise it will easily lead to rooting, affecting its yield and quality. 2, nitrogen, phosphorus, potassium with the application. Nitrogen can promote the growth of leaves and synthesize more nutrients; phosphorus is conducive to nutrient operation, improve quality, has a great influence on the initial growth of carrots, has little effect in the meat enlargement period, and is usually applied in basal fertilizer; potassium can promote root formation layer The mechanization activities have obvious effect on increasing production. Generally speaking, the production of 1000 kilograms of carrots in mu requires absorption of 2.40-4.30 kg of nitrogen (N), 0.70-1.70 kg of phosphorus (P2O5), and 5.70-1.70 kg of potassium (K2O), and the ratio is 1:0.40:2.6. All required phosphate fertilizers can be applied as base fertilizer; part of the required nitrogen fertilizer and potassium fertilizer is applied as base fertilizer, and the rest can be applied as top dressing when the leaf growth is prosperous, the root diameter of the meat reaches 0.60 cm, and the roots of the meat are swollen. Fertilizer after spraying 800 times the new high-fat membrane fertilizer utilization. 3, the application of micro-fertilizer. Carbohydrate absorbs more calcium. When the calcium content is too high, carrot sugar content and carotene content will decrease. When calcium deficiency is caused, it will cause hollow disease. Carrots will absorb less magnesium, the more magnesium content, the sugar content and the carotene. The more the content, the better the quality. Applying calcium magnesium phosphate fertilizer in basal fertilizer can increase the content of calcium and magnesium in the soil. For boron fertilizer, boric acid solution or borax solution was sprayed twice at the seedling stage and the leaf growth stage, and twice during the root swelling stage, and with the new high-fat membrane 800 times solution. Fertilizer effective ingredient utilization, and in the beginning of the expansion of the fleshy root should be promptly sprayed fruit Guo Zhuang Ti Ling underground fruit nutrient transportation catheter thickening, increase fruit enlargement vitality, so that the carrot fruit surface smooth, fruit-type bodybuilding, high quality and high yield.
