Description

Pollen nutrient solution for improving pollination rate of pear trees
Technical Field
The invention relates to the field of pear tree planting, in particular to a pollen nutrient solution for improving pollination rate of pear trees.
Background
Pear is one of main planted fruit trees in China, and the self-pollination fruit setting rate in the field is extremely low. Therefore, the pollinator needs to be reasonably configured or artificially assisted pollinated in production. The pollination trees are configured to carry out natural pollination mainly by using the pollination capability of insects, so that labor and force are saved, but the pollination and fertilization are poor due to the influence of weather. The artificial pollination mode in the artificial supplementary pollination method has the advantages of strong selectivity, high accuracy, small pollen consumption, short operable time, long time, more labor and more limited conditions. The liquid pollination is a novel pollination technology, has the characteristics of high pollination speed and labor saving, can increase the water and nutrient of the stigma, and prolongs the pollination fertilization time of the stigma. However, in the prior art, the pollination rate of pollen is not high when the pollen nutrient solution for pear trees is used, and the pollen is used in a large amount in the proportioning process of the pollen nutrient solution, so that the pollen is wasted, and the cost is increased.
Disclosure of Invention
In order to solve the problems, the invention provides a pollen nutrient solution for improving the pollination rate of pear trees.
In order to realize the purpose, the invention adopts the technical scheme that:
a pollen nutrient solution for improving pollination rate of pear trees is prepared from 0.1% by mass of forchlorfenuron, potassium dihydrogen phosphate, polydopamine, fructo-oligosaccharide, trehalose and water.
Preferably, the catalyst is prepared from the following raw materials in percentage by mass:
0.1% of forchlorfenuron 0.4-0.6%; 1.5-5.5% of monopotassium phosphate; 0.5-1% of polydopamine; 6-10% of fructo-oligosaccharide; 3-5% of trehalose and the balance of water.
Preferably, the catalyst is prepared from the following raw materials in percentage by mass:
0.1% of forchlorfenuron 0.4%; 5.5 percent of monopotassium phosphate; 0.5% of polydopamine; 6% of fructo-oligosaccharide; trehalose 3%, the balance water.
Preferably, the catalyst is prepared from the following raw materials in percentage by mass:
0.1% of forchlorfenuron 0.6%; 1.5 percent of monopotassium phosphate; 1% of polydopamine; 10% of fructo-oligosaccharide; 5% of trehalose and the balance of water.
Preferably, the catalyst is prepared from the following raw materials in percentage by mass:
0.1% of forchlorfenuron 0.5%; 3.5 percent of monopotassium phosphate; 0.75% of polydopamine; 8% of fructo-oligosaccharide; trehalose 4% and the balance water.
The invention has the following beneficial effects:
through the optimization of the formula of the pollen nutrient solution, pollen can be stably adsorbed on female flower stigmas, so that the pollination effect is ensured, the pollination fruit setting rate of pear trees can be obviously improved, and the using amount of the pollen can be reduced.
