Alkaline improver adopting phosphate fertilizer as substrate and application method of alkaline improver

Abstract

The invention belongs to the technical field of soil improvers and discloses an alkaline improver adopting phosphate fertilizer as a substrate and an application method of the alkaline improver. Through application of the improver, soil nutrients can be increased, the enzyme activity can be improved, the growth of tea trees is facilitated, and the absorption of heavy metals by plants is inhibitedto some extent. When the alkaline improver is applied in combination with a biological conditioner and calcium superphosphate, the content of soil available phosphorus and the content of organic matter in the next year are increased by 31.5% and 17.2% respectively than those in the last year. When the alkaline improver is applied in combination with limestone and calcium superphosphate, the content of an SOD enzyme in tea is increased by 34%. After the application of the improver, the time duration of a soil pH adjustment effect on a tea garden is long, the soil physical and chemical properties and the enzyme activity are improved, the quality of finished tea products of the tea trees is also improved, the yield of tea in the tea garden is effectively increased, and the quality of tea in the tea garden is effectively improved. The oil condition of the tea garden is observed after the alkaline phosphorus-containing soil improver is added into a field test field, the change of soil fertility and heavy metal content after the phosphorus-containing improver is applied to the soil is observed, and the persistence of the soil improvement effect of the phosphorus-containing improver is explored.

Description

technical field [0001] The invention belongs to the technical field of soil improvers, and in particular relates to an alkaline improver with phosphate fertilizer as a substrate and an application method thereof. Background technique [0002] Currently, the closest prior art: [0003] There is a long record of drinking tea in Chinese history. Tea is a traditional beverage in my country. Tea trees are perennial crops. The goal is to harvest young shoots. They have strong secondary metabolism. The soil of tea gardens is different from that of other field crops. The growth of tea trees is good or bad and the quality of tea is high or low. have a close relationship. [0004] Tea trees are acid-loving plants, but in recent years, due to acid rain, the metabolism of tea trees has caused problems such as soil acidification and nutrient loss in tea gardens. The soil of the tea garden is weakly acidic, and tea trees can grow only when the pH of the soil is 4.5-6.5, and the optimum ...
