There are four ways to improve the quality of strawberry in greenhouses
Enhanced light illumination not only directly affects the photosynthesis of the plants, but also indirectly affects the fruit coloration. If the light is insufficient before and after flowering, it will affect the accumulation of starch in the pollen, so that the energy of the pollen germination is not enough, resulting in a reduced germination rate, thereby affecting fertilization, resulting in malformed fruit. Therefore, when covering the shed, you should use a polyethylene with no light transmission film. Always clean the dust on the film and hang a 2 meter high mirror reflective film on the wall. In this way, not only can increase the utilization of light, but also can increase the shelf temperature 2 °C ~ 3 °C.
The greatest benefit of covering the plastic film cover is to reduce the air humidity, reduce the pests and diseases, effectively prevent the fruit from touching the ground, and avoid producing soft fruit, and the fruit surface is clean. The best way to use water irrigation drip irrigation, flowering results can not flood irrigation, excessive humidity caused by pollen is not easy to disseminate, affect the normal fertilization, increase the production of deformed fruit. Therefore, timely ventilation and humidity should be maintained, but the temperature should be maintained at 20 °C ~ 25 °C, in order to facilitate pollen germination. During the flowering period, 0.5% potassium dihydrogen phosphate or 0.2% borax + 0.4% potassium dihydrogen phosphate + 0.5% sugar solution may be sprayed on the leaf surface to improve fruit quality.
During the flowering period of the auxiliary pollination, a box of bees can be stocked in the shed to facilitate pollination, but the temperature should be controlled so that the bees can normally move, and pollination can also be artificially assisted.
Reasonable spraying of pesticides during flowering of strawberries can easily induce plants to produce malformed fruit, and at the same time affect bee pollination. Therefore, try not to use dipterex, mancozeb WP, etc. before spraying to make the plants produce malformed fruit. Remove the beehive from the shed before spraying, and return it to the shed within about 1 week after spraying.
