Embodiment 1

[0023] A high-yield cultivation method for lychees, the first time to choose to fertilize before flowering, apply phosphorus fertilizer and potassium fertilizer, apply 0.1kg of phosphorus fertilizer and 0.5kg of potassium fertilizer to each plant, and spray boron fertilizer and potassium dihydrogen phosphate on the leaves at the same time, apply to each plant 0.1kg; for the second time, fertilize within 15 days after the litchi flowers fall, mainly urea, phosphorus fertilizer, and potassium fertilizer, and apply 0.2kg of urea, 0.3kg of phosphorus fertilizer, and 0.3kg of potassium fertilizer to each plant; the third choice is before fruit picking The 7-day fertilization is mainly based on nitrogen, phosphorus and potassium compound fertilizer, and 1kg is applied to each plant.

Embodiment 2

[0025] A high-yield cultivation method for lychees, the first time to choose fertilization before flowering, apply phosphorus fertilizer and potassium fertilizer, apply 0.5kg of phosphorus fertilizer and 0.5kg of potassium fertilizer to each plant, and spray boron fertilizer and potassium dihydrogen phosphate on the leaves at the same time, apply to each plant 0.1kg; for the second time, fertilize within 12 days after the litchi flowers fall, mainly urea, phosphorus fertilizer, and potassium fertilizer, and apply 0.3kg of urea, 0.2kg of phosphorus fertilizer, and 0.4kg of potassium fertilizer to each plant; the third choice is before fruit picking 15 days of fertilization, mainly based on nitrogen, phosphorus and potassium compound fertilizers, applying 2kg per plant.

Embodiment 3

[0027] A high-yield cultivation method for lychee, the first time to choose fertilization before flowering, apply phosphorus fertilizer and potassium fertilizer, apply 0.3kg of phosphorus fertilizer and 0.2kg of potassium fertilizer to each plant, and spray boron fertilizer and potassium dihydrogen phosphate on the leaves at the same time, apply to each plant 0.4kg; for the second time, fertilize within 10 days after the litchi flowers fall off, mainly urea, phosphorus fertilizer, and potassium fertilizer, and apply 0.3kg of urea, 0.3kg of phosphorus fertilizer, and 0.2kg of potassium fertilizer to each plant; the third choice is before fruit picking 15 days of fertilization, mainly based on nitrogen, phosphorus and potassium compound fertilizers, applying 1.5kg per plant.

Abstract

The invention belongs to the technical field of fruit tree planting, in particular to a method for high-yield cultivation of litchis. The method for the high-yield cultivation of the litchis is characterized in that rational fertilization is carried out in a cultivation process of the litchis, and the principles of frequently fertilizing and thinly fertilizing are followed; a whole year mainly includes three fertilization periods, the first time of fertilization is carried out before flowering, the second time of fertilization is carried out within the 10th day to the 15th day ever since litchi flowers wither, and the third time of fertilization is carried out in the period of 7 to 20 days before fruit harvesting. Compared with the traditional fertilizing method, the method provided by the invention can improve the yield and quality of the litchis.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, in particular to a method for fertilizing litchi in high-yield cultivation. Background technique [0002] Litchi (Litchi chinensis Sonn.) is a kind of tropical fruit widely cultivated in tropical and subtropical regions of my country. It is mainly distributed in Guangdong, Guangxi, Fujian, Hainan and other places. Its planting area and output account for about 80% and 65% of the world respectively. Fresh lychee fruit is good in color, fragrance, taste, shape, and is known as the "treasure among fruits". It has high nutritional value and is deeply loved by people. Litchi can not only be eaten as a fruit, but also as a medicinal material, which has the effects of treating small intestinal gas pain, heart gas pain, astringent and pain relief. Litchi is a high-quality food material, and its peel is dark reddish brown. The texture of the peel is highly corrosion-resistant and elegant. At ...
