Pollination as soon as possible after flowering is better as it is pollinated. The fruit obtained after pollination on the fourth day of flowering was poorly developed, and the fruit was small, and the pollination and fruit set rate decreased significantly after five days.
Pollen collection and treatment It is best to pick the buds that need to be placed, and the buds that are too tender are of poor quality. After harvesting the flowers, remove the pink anthers from the buds as soon as possible, spread them on the paper, and dry them, so that the yellow pollen in the anthers can be dispersed. The pollen can also be dried in a thermostatic chamber at 20°C to 25°C to dry the pollen, speeding up the opening of the pollen and dispersing the pollen. After the pollen has dried, it is placed in a vial for use. The amount of pollen that each flower needs when pollinating is very small. In order to save pollen, a filler such as milk powder, lotus root powder or talc powder may be added to pear pollen before pollination.
Pollination methods can be diluted with pollen in a gauze bag, and then tied to the club head, gently beat the pole with a wooden stick, so that the pollen was removed on the stigma of the flowers, in this way 1 hectare (15 acres) fruit pear orchard About 750 grams of pollen are needed. The pollen can also be mixed into a 15% sucrose solution and sprayed on the stigma of the flower with a sprayer. One to two halves of pear orchard require 1200 to 1500 grams of pollen. You can also use the brushhead or pencil eraser to pollinate flowers.
Pollen trees are misconfigured or inadequate orchards. A thorough solution is to pollinate varieties. For simplicity, the squid of the pollinated variety can be cut, inserted in a bottle containing water, and hung on the upper part of the pear tree to be pollinated. A large tree needs to hang 4 to 5 bottles. This method is simple, but the effect is not as good as the above; in addition to the above methods, bees can be pollinated. It is suitable for the pollination tree to occupy more than 20% of the park orchard with even distribution, to induce bee before flowering, and generally to use a box of bees per 10 acres.
Soiless Cultivation hydroponic pipe planting vegetables, the whole growth process does not touch the soil, can reduce more than 70% soil-borne diseases. Agriculture Facility can not only reduce the occurrence of pests and diseases, but also greatly increase the yield of vegetables. Through the three-dimensional cultivation mode, the land utilization rate can be improved, and the harvest yield is 2 ~ 3 times that of the open field planting. The whole set of cultivation facilities NFT Hydroponic Channel is placed in the ecological restaurant, office, living room and other places, which can not only pick and watch, but also increase the added value of its products.
Advantages of Soilless Culture
1.Save land,no soil is needed.
2.All the growing conditions can be controlled with machine.
3.Stable operation, long use life and high productivity.
4.Environment protection.
5.Plants grow healthier and easy to harvest.Widely used in Tomato And Cucumber Greenhouse and Glass Greenhouse
