Problems solved by technology

[0003] Excessive nitrogen, phosphorus, and potassium fertilization is common in the process of honey pomelo planting, which has brought about a series of environmental problems. According to the preliminary investigation of our research group, the nitrate content of residents' domestic water exceeds the standard seriously
At the same time, it is common for fruit growers to have the problem that the nutrient supply and ratio are inconsistent with the law of crop nutrient demand. For example, according to the survey result

Abstract

The invention discloses a honey pomelo complete set fertilizer and a using method thereof. The complete set fertilizer is composed of a pre-harvest fertilizer, a spikelet-promoting fertilizer, a fruit-stabilizing fertilizer and a fruit-swelling fertilizer, wherein the pre-harvest fertilizer and the fruit-swelling fertilizer comprise the following active ingredients in percentage by weight: 13-17%of nitrogen, 13-17% of phosphorus pentoxide and 13-17% of potassium oxide; the spikelet-promoting fertilizer comprises the following active ingredients in percentage by weight: 25-26% of nitrogen, 10-14% of phosphorus pentoxide and 7-11% of potassium oxide; and the fruit-stabilizing fertilizer comprises the following active ingredients in percentage by weight: 15-18% of nitrogen, 5-7% of phosphorus pentoxide and 20-25% of potassium oxide. The honey pomelo complete set fertilizer can meet the nutrient requirements and nutrition functions of honey pomelos at different growth stages, the soil nutrient supply rule is matched, the yield and the quality of the honey pomelos are improved, the nutrient utilization rate and the income are increased, the yield per mu is increased by 350-910kg compared with that in custom fertilization of peasants, the fertilizer cost is saved by 442-677yuan, the income per mu is increased by 5786-12009yuan, and the nitrogen fertilizer utilization efficiency is increased by 86-152%. Therefore, the honey pomelo complete set fertilizer has an extremely high actual application value and wide market application prospect.

Description

technical field [0001] The invention belongs to the technical field of pomelo planting, and in particular relates to a pomelo set fertilizer and its application method. Background technique [0002] Honey pomelo is a well-known local traditional fruit originally produced in Pinghe County, Fujian Province, and has a cultivation history of more than 500 years. During the Qianlong period of the Qing Dynasty, it was listed as a tribute to the court, and Emperor Tongzhi presented a seal of "Xipu Letter" and a green dragon flag as a sign of tribute and a ban. Honey pomelo has the characteristics of good quality such as storage resistance, thin skin, juicy, sweet taste, and fleshy mouth, so it has high economic added value. It has developed rapidly in recent years and has been widely introduced in Guangdong, Hainan, Sichuan and other provinces. The national planting area is about 1.6 million mu. [0003] Excessive nitrogen, phosphorus and potassium fertilization in the process of...
