Embodiment 1

[0046] Take the mango orchard in Xindan Village, Foluo Town, Ledong City, Hainan Province as an example:

[0047] One crop per year, one year is a production cycle, the amount of nitrogen applied in each production cycle is 108kg / ha, the distance between plants and rows is 4m×5m, the variety is Tainong No. 1, and the tree age is 20 years old.

[0048] Tip fertilizer: N: 74.24g per plant before the fruit tree shoots, P 2 o 5 : 14.85g, K 2 O: 51.97g, where N:P 2 o 5 :K 2 O=1:0.2:0.7, such as urea 160g, potassium dihydrogen phosphate 28.6g, potassium sulfate 81.3g, apply in circular furrows or strips along the drip line of the tree crown, mix the fertilizer with the soil in the fertilization ditch, and use fine fertilizer after fertilization Soil and litter cover;

[0049] Flower-promoting fertilizer: apply N: 69.6g per plant before flowering, P 2 o 5 : 34.8g, K 2 O: 90.48g, where N:P 2 o 5 :K 2 O=1:0.5:1.3), such as urea 150g, potassium dihydrogen phosphate 66.9g, po...

Embodiment 2

[0056] Take Longguang Mango Garden in Wenluo Town, Lingshui County, Hainan Province as an example:

[0057] One crop per year, one year is a production cycle, the amount of nitrogen applied in each production cycle is 108kg / ha, the distance between plants and rows is 4m×5m, the variety is Tainong No. 1, and the tree age is 24 years old.

[0058] Tip fertilizer: N: 77.34g per plant before the fruit tree shoots, P 2 o 5 : 15.47g, K 2 O: 54.14g, where N:P 2 o 5 :K 2 O=1:0.2:0.7, such as urea 166.7g, potassium dihydrogen phosphate 29.7g, potassium sulfate 84.7g, apply in circular furrows or strips along the drip line of the crown, mix the fertilizer with the soil in the fertilization ditch, and use it after fertilization Fine soil and litter cover;

[0059] Flower-promoting fertilizer: N: 72.56g per plant before flowering, P 2 o 5 : 36.28g, K 2 O: 94.33g, where N:P 2 o 5 :K 2 O=1:0.5:1.3), such as urea 156.4g, potassium dihydrogen phosphate 69.8g, potassium sulfate 135...

Abstract

The invention discloses a mango stage nutrition formula and a formula use method. The mango stage nutrition formula comprises a shoot accelerating fertilizer, a flower accelerating fertilizer and a fruit strengthening fertilizer, N:P2O5:K2O in the shoot accelerating fertilizer is 1:0.2:(0.7-0.9), N:P2O5:K2O in the flower accelerating fertilizer is 1:0.5:(1.1-1.3), and N:P2O5:K2O in the fruit strengthening fertilizer is 1:0.2:(1.5-1.8). The use method of the formula comprises the following steps: applying a shoot promoting fertilizer, namely applying the fertilizer containing N, P2O5 and K2O nutrients to each fruit tree before sprouting of the fruit tree; applying the flower forcing fertilizer, namely, applying a fertilizer containing N, P2O5 and K2O and boron fertilizer to each plant before flowering; and applying the fruit strengthening fertilizer, namely, applying a fertilizer containing N, P2O5 and K2O and magnesium fertilizer to each plant in the fruit expanding period. The mango stage nutrition formula provided by the invention can meet the nutrient requirements of mangoes in different growth stages throughout the year.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a mango stage nutritional formula and a method for using the formula. Background technique [0002] Mango is an evergreen tree of Anacardiaceae native to India. Its fruit is very popular because of its high sugar content, vitamin A, B, and C, and rich mineral elements such as phosphorus, iron, and calcium. It has the reputation of "tropical fruit king". The main producing countries are India, Brazil, the Philippines, China, etc. The main planting areas in my country are distributed in Hainan, Taiwan, Guangdong, Guangxi, Yunnan, Sichuan, Guizhou, Fujian and other places. [0003] Hainan is located in the tropics and has abundant water and heat conditions, which provide good natural climate conditions for the growth of mangoes. Among them, Tainong No. 1 is currently the main variety in Hainan Province, accounting for about 70% of the total planting area. Reasonable cultivation managemen...
