Abstract

The invention discloses a fertilizing method for improving the utilization rate of fertilizer for kidney beans. According to the fertilizing method for improving the utilization rate of the fertilizer for kidney beans, firstly, the soil where the kidney beans are to be planted is tested for formulated fertilization, and the standard fertilizing amount of the soil for the kidney beans is calculated and determined; tomato straw air dry matters are cut off two or three weeks before the kidney beans are planted, after the cut tomato straw air dry matters are evenly scattered into the soil of lands according to the amount of 200 kilogram per mu, and the soil is turned over, the soil is irrigated one time, base fertilizer is applied after the lands are dried in the air, nitrogen, phosphorus and potassium is respectively 10%, 60% and 10% of the standard fertilizing amount, and additional fertilizer is applied six times. The fertilizing method for improving the utilization rate of the fertilizer for kidney beans can effectively solve the problem of blind fertilization of vegetable growers, improves the utilization rate of fertilizer by 30-40% compared with a traditional fertilization method, improves the agronomy utilization rate by 30-43% compared with a conventional fertilization method, improves the commodity rate and the output of kidney beans, improves the quality of kidney beans, and enables planting of kidney beans to have good application prospects in the Southern like the Guangdong province.

Description

Technical field: [0001] The invention belongs to the fields of crop production technology and fertilizer application technology, and in particular relates to a fertilization method for improving the utilization rate of bean fertilizer. Background technique: [0002] Improper management of nutrients such as fertilizers has caused serious resource and environmental problems. With the continuous increase in the amount of chemical fertilizers, their utilization rate and utilization efficiency have gradually declined. The intensive vegetable production base in the Pearl River Delta region has excessive fertilization and high multiple cropping index, resulting in high nutrient accumulation in the vegetable field, with an average nitrogen application rate of 328.7kg / hm 2 , the highest nitrogen rate is 1732.5kg / hm 2 , The nitrogen fertilizer use rate was 12.9%, which was far lower than the national nitrogen fertilizer use rate of 27.5% in the current season. The highest total phos...
