In the cultivation of eggplants in the greenhouse, the phenomenon of stagnation often occurs, mainly due to the following reasons.
1. Spend too little time when eggplant petals all turn purple to open for a total of 3 days, but the best treatment is to open the flowers on the same day. If the flower is not open, it is easy to form a regular eggplant.
2. The concentration of anther liquid is too high. The concentration of anther liquid is reasonably adjusted with the temperature. When the temperature is high, the concentration should be decreased. When the temperature is low, the concentration should be increased. If the temperature in spring is much higher than in winter, the concentration of the anther liquid should be low. Because the temperature is high, the transpiration is strong, the water evaporates quickly, and the concentration of the anther liquid is relatively large, and it is easy to form a stalemate.
3, high-temperature conditions point flower eggplant flower suitable temperature is 23 °C -28 °C, more than 30 °C should stop spending, if not finished, should be in the afternoon after the temperature drop.
4. Overgrowth of nutrients and excessive growth of nutrients cause insufficient reproductive growth. After the flowers are used, the eggplants do not receive sufficient nutrients to form a stalemate. In this case, inhibitors such as methiazin or quercetin should be sprayed to reverse the phenomenon of overgrowth of nutrients, and then flowering.
5. Boron-boron-boron is directly involved in flower bud differentiation. If the flower bud differentiation period lacks the supply of boron fertilizer, it is easy to form a stylized flower with short stylus or stigma turning dark. Even if the deformed flower stays at a point, its growth is very slow, and it is easy to form a stale fruit. .
