Problems solved by technology

[0003] In the process of planting pear trees, in addition to spraying drugs to prevent and control diseases and insect pests, attention should also be paid to the correct use of base fertilizer and top dressing, so as to ensure the fruit setting rate and yield of pear trees. The base fertilizer is mainly decomposed human excrement or manure. For cattle, sheep, chicken, pig manure, etc., the topdressing includes the part that is applied to the soil and the part that is sprayed on the foliage. When the topdressing fertilizer for foliar spraying is used, the formula chosen by various farmers is relatively random, and the dosage is also different. The effect of foliar topdressing is not very good

preparation example Construction

[0024] The preparation method of the above-mentioned foliar topdressing for improving the fruit setting rate of pear trees comprises the following steps:

[0025] (1) Weigh potassium dihydrogen phosphate, borax, copper sulfate, quicklime, zinc sulfate, ferrous sulfate, urea, sucrose and ammonium molybdate, set aside;

[0026] (2) Add copper sulfate and quicklime to 100 times the weight of water, stir well and set aside;

[0027] (3) Add potassium dihydrogen phosphate, borax, zinc sulfate, ferrous sulfate, urea, sucrose and ammonium molybdate into clear water with 100 times the weight, stir well and set aside;

[0028] (4) Mix the products of step (2) and step (3) in a weight ratio of 1:1 to obtain a finished product.

Embodiment

[0030]

[0031] 1. Add copper sulfate and quicklime to 100 times the weight of water, stir well and set aside;

[0032] 2. Add potassium dihydrogen phosphate, borax, zinc sulfate, ferrous sulfate, urea, sucrose and ammonium molybdate into 100 times the weight of clean water, stir well and set aside;

[0033] 3. The products of step (2) and step (3) are mixed in a weight ratio of 1:1 to obtain a finished product.

[0034] Spray 4 times throughout the year, choose sunny days with little wind, evenly spray the crown, 2 times in the growth period, 2 times in the later period, and carry out the last time 20 days away from the fruit harvest period.

[0035] After spraying the foliar topdressing of the present invention, the fruit setting rate increases by 10%, and the yield increases by 8%.

[0036] In the present invention, potassium dihydrogen phosphate, borax, copper sulfate, quicklime, zinc sulfate, ferrous sulfate, urea, sucrose and ammonium molybdate are used as raw mater...

Abstract

The invention relates to a foliar top-dress fertilizer used for improving pear tree fruit setting rate. The fertilizer comprises potassium dihydrogen phosphate, borax, copper sulfate, quicklime, zinc sulfate, ferrous sulfate, urea, sucrose and ammonium molybdate. With the fertilizer provided by the invention, the properties of components are stable, and pear leaves are not damaged. With the cooperation of copper sulfate and quicklime, a sterilization effect is provided. Potassium dihydrogen phosphate, urea and ammonium molybdate can supplement nitrogen, phosphorus and potassium needed by pear trees. With borax, pear tree fruit shrink disease rate can be substantially reduced. Zinc sulfate has good treatment effect against pear tree leaf spot and little-leaf diseases. Ferrous sulfate helps in correcting pear tree iron-deficiency chlorotic yellowing. With sucrose, pear sweetness can be enhanced. With the components, pear tree fruit setting rate can be improved comprehensively. Pear yield can be improved, and grower income can be improved.

Description

technical field [0001] The invention belongs to the technical field of pear tree cultivation, in particular to a foliar topdressing fertilizer for improving the fruit setting rate of pear trees and a preparation method thereof. Background technique [0002] Pear tree is a perennial deciduous fruit tree belonging to the family Rosaceae. There are about 35 native species in the world. They are wildly distributed in Europe, Asia and Africa. The tree's full bloom. The fruit of the pear tree is pear, which is crispy and juicy, sweet and sour. It contains a lot of vitamin A, carotene, protein, sugar, calcium, phosphorus and other nutrients. It has a good therapeutic effect on the treatment of heart disease, dizziness and tinnitus. The elderly eat more pears, which can help purify human organs and soften blood vessels. [0003] In the process of planting pear trees, in addition to spraying drugs to prevent and control diseases and insect pests, attention should also be paid to th...
