Pay attention to how to distinguish high quality kiwifruit pollen! Good performance of pollination and fertilization

Actinidia chinensis mainly uses commercial pollen for artificial assisted pollination. At present, there are many brands of commercial pollen on the market. When purchasing commercial pollen, the majority of fruit farmers must pay attention to it, so as to avoid buying inferior kiwifruit pollen, resulting in bad pollination of flowers and fruits, resulting in huge losses. Here we teach you how to identify high quality and reassuring kiwifruit pollen!
1. Look at the color, the pure pollen is grayish-white, the higher the purity, the whiter the color, the more impurities, the deeper the brown degree.
2. The more pure the pollen is, the easier it will disperse when it is dumped. The pollen containing impurities is blocky, shaking the bottle of the pollen. The pure pollen is in a flowing state, while the poor purity is in a poor flowing state.
3. Smell, with fragrant leaves and grass flavor, easy to pungent nose;
4. Touch the texture, high-quality pollen feel smooth and delicate;
5. Measure the viability. After culturing, the viability of good pollen can reach more than 70% under the microscope.
The second day after pollination, the stigma of female flowers began to wither and the color of petals turned yellow, which indicated that pollination and fertilization were good.
