Greenhouse sweet melon flowers
Muskmelon is a typical insect-like flower. After pollinating by bees and other insects, the ovary can expand to form fruit. In greenhouse cultivation, due to the lack of insect pollination, necessary measures should be taken to promote sitting. It is commonly used in production to promote sitting guarana. How to science flowers?
1. Before diluting the water with water, a bag (5 ml) of guarana was diluted with water according to the instructions for use to the desired concentration. The optimum concentration of sitting guayan can be greatly affected by the temperature. The small concentration can not play the role of fruit set, and the concentration is large and it is easy to produce malformed melon. Under normal circumstances, when the temperature is 12°C, each bag of melons will contain 250-300 ml of water, 13-35°C will have 400-500 ml of water, and 26-300°C will have 700-800 ml of water, 30°C. Water at 900-1000 ml at 35°C.
2. Dipping time: generally between 9:30am and 3pm. If the time is too early or too late, there is a large mist in the greenhouse. Water droplets form on the surface of the melon tire. After the dipping, the melon liquid is uneven, the concentration is inconsistent, and the melon growth rate is unbalanced. quality.
3. Dipping method: Select the female flower of the opening day, and dip the melon with a diluted solution. The time should be 2 to 3 seconds. It should not be too long. If it is too long, it will produce phytotoxicity. At the same time, after licking the liquid, gently prick the handle with your finger and drop the medicine hanging under the baby's fetus to prevent melon malformation caused by uneven liquid.
