Problems solved by technology

In these provinces, mango planting areas are basically dominated by mountains and slopes. A large number of mountain and slope orchards have the same problems: poor soil fertility, lack of organic matter, thin soil layer, steep slope, no water retention, no fertilizer retention, and soil erosion. Seriously, the most important thing is that the time and space of water do not match, and the utilization rate of fertilizer and water resources is extremely low, which has caused great troubles to the mango industry
Patent CN107980317A provides a method that can realize the integrated automatic irrigation of water and fertilizer during mango cultivation. The water pump is used as the transmission power, and then the computer system is regulated to transmit water and fertilizer. It uses thin water pipes for irrigation and spray irrigation, so that a large part of the water and fertilizer Runoff and evaporation on the surface of the orchard, only a small part can reach the roots and be absorbed, and the water and fertilizer utilization rate is not high

Abstract

The invention provides a water and fertilizer application method of mountain mangoes and application. Nutrients and moisture required by the mountain mangoes are timely, effectively and continuously provided by accurately regulating and controlling the water and fertilizer ratio and through a water and fertilizer slow-control device according to a growth and development law, a nutrient absorption law and a whole growth period growth regulation and control law of the mountain mangoes; slow-control fertilizer application and water supplementation are carried out, the problem that moisture, fertilizer, time and space of a mountain mango garden cannot be effectively and uniformly controlled is effectively solved, high and excellent yield of the mountain mangoes is facilitated, and yield and income increase of the mountain mangoes is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a water and fertilizer application method and application of mountain mango. Background technique [0002] Mango is a famous tropical fruit and one of the top ten fruits in the world. Its output ranks fifth after citrus, bananas, grapes and apples. Because of its beautiful oval fruit, fine and smooth flesh, rich and refreshing juice, unique flavor and rich nutrition, it is deeply loved by people, so it is known as the "king of tropical fruits". my country's mango planting areas mainly include: Taiwan, Guangdong, Guangxi, Hainan, Yunnan, Sichuan, Fujian and other provinces and regions. Mango planting has become an important tropical economic crop in China and is one of the important supports for the agricultural economy in some areas. In these provinces, mango planting areas are basically dominated by mountains and slopes. A large number of mountain and slope orchar...
