Position and flow double-controlled liquid pollination device and method for adjusting fruit setting rate of fruit trees

Abstract

The invention discloses a liquid pollination spray device and a method for liquid pollination by the device. The device comprises a liquid storage barrel and a spray rod connected with the liquid storage barrel, at least one sprayer is arranged on the spray rod, a protective cover is arranged on each sprayer, one end of the protective cover is fixed onto the spray rod, the other end of the protective cover is open, and the open end of the protective cover is provided with a louver cover. The length of the spray rod and the number of the sprayers are determined according to the height of a fruit tree to be pollinated and flower distribution positions during pollination, the angles of blades on the louver cover are adjusted according to the load of the fruit tree, and the concentration of pollens in liquid pollination fluids is adjusted according to required fruit setting rate. Labor intensity is greatly reduced, and efficiency is improved. Flexible adjustment can be performed accordingto the load of an orchard. Fruits are set by the pollens, the device is simple, practical, convenient to use, wide in applicable range and low in cost, and orchard pollination and flower and fruit thinning labor can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of pollination of fruit trees, in particular to a device and method for adjusting the fruit setting rate of fruit trees by liquid pollination with double control of position and flow. Background technique [0002] Plant self-incompatibility is a ubiquitous self-fertilization-limiting mechanism in angiosperms, which prevents pollen tubes of the same genotype from growing and fertilizing normally in pistils. The reaction involves more than 70 families and more than 250 genera. The occurrence of self-incompatibility prevents inbreeding, promotes cross-pollination, and is beneficial to species diversity. According to the different controlling factors, the types of self-incompatibility can be divided into sporophyte and gametophyte. Gametophyte self-incompatibility means that during the interaction between pollen and pistil, the behavior of pollen is determined by the nature of the protein in the inner wall of ...

Problems solved by technology

However, with the existing technology, the operation of flower thinning and fruit thinning is completely dependent on manual operation, which requires a lot of labor. With the rising labor cost, manual flower thinning and fruit thinning has become a bottleneck problem restricting the efficiency of orchards.

Although the cost of chemical flower thinning and fruit thinning is low, the effect is extremely unstable and has not been widely promoted for many years
