Abstract

The invention relates to nutritional fertilizer special for citrus grandis. The fertilizer can be supplied according to different nutrient requirements at different growth periods of the citrus grandis, is applied according to three periods of nutritional growth period, flowering period and fruiting period, can meet the nutrient requirement of the citrus grandis in all periods and is based on high-quality organic fertilizer so as to solve the problems of low quality, unbalanced nutrient structure and the like of the fertilizer during planting of the citrus grandis and guarantee high quality, stable production and high yield of the citrus grandis.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special compound fertilizer for Shatian pomelo. Background technique [0002] Shatian pomelo (Citrus grandis) is one of the famous fruits in Guangdong. At present, Shatian pomelo has been using the traditional phosphate fertilizer, common compound fertilizer and a small amount of urea combined with multiple applications, and insufficient attention has been paid to the balance of nutrient elements and the harmlessness of fertilizer quality. The backward cultivation and management technology is an important reason for the poor development of Shatian pomelo. At present, there is no pollution-free and long-acting special compound fertilizer suitable for the growth characteristics of Shatian pomelo and improving the nutritional quality in the domestic market. Therefore, according to the nutritional environment conditions for the growth of pomelo, it is an urgent n...
