Temperature and light will also affect the fruit of lotus. The place where lotus flowers are planted needs sufficient light, and cloudy days will affect flowering and fruiting. Temperature is also an important factor affecting the fruit of lotus. The optimum growth temperature of lotus fog is 25-30℃, and freezing injury is easy to occur below 10℃.
Shoot control is one of the main measures to promote flowers and protect fruits of lotus fog. It can control the growth of branches, prevent excessive growth of branches, lead to excessive closure of fruit trees, affect photosynthesis and reduce flowering rate. In the process of lotus growth, it is necessary to observe the growth situation at any time and artificially promote flowers and protect fruits. Specifically, the following tasks should be done well: 1. Prune this tree. Before pruning the lotus, it is best to spray some drugs to control the growth of the treetops. After spraying, corresponding pruning measures should be taken according to the development of trees.
The particularity of fog-induced flowering lies in the promotion and induction of other plant growth substances besides the use of high-concentration organophosphorus pesticides. Some growers believe in triamcinolone acetonide and ignore cytokinin.
Lotus root system distribution is shallow, like wet, afraid of drought. In the stage of growth and fruiting, it is necessary to maintain a certain soil water content and water it frequently. Water should be properly controlled when the fruit is ripe. The temperature in winter and spring is low, the air humidity in the greenhouse is high, and the evaporation of plants is small. You can choose some strong branches and then use air layering to promote rooting. Finally, cut off the branches full of roots, turn them into new potted plants, and raise them in larger flowerpots, so that the lotus can continue to blossom and bear fruit.
