How to promote flower bud differentiation of lotus flower

Lianwu is a very popular fruit, which has high nutritional value, can be used in medicine to treat diseases, and has a certain ornamental value. the flower bud differentiation of lotus in the growing period is related to the yield and quality in the later stage. So how does lotus fog promote flower bud differentiation? Let's get to know it.

1. Control fertilizer

Nitrogen fertilizer will promote the vegetative growth of plants, so the control of fertilizer is to control the application of nitrogen fertilizer. 1-2 months before lotus fog catalysis, a small amount of nitrogen fertilizer is not applied to plants with weak tree potential, except nitrogen fertilizer or organic fertilizer. Only phosphorus, potassium and trace elements are needed. If the germination time is at the end of September, when the temperature is high, early application of nitrogen fertilizer will cause the plant to sprout a large number of new shoots, resulting in germination failure, so it is necessary to wait until the completion of plant germination before applying nitrogen fertilizer.

2. Girdling

Girdling can truncate the nutrient transport of the plant, inhibit the vegetative growth of the plant, and promote its reproductive growth. Generally, one month before budding, girdling is carried out at 30 cm of the trunk according to the ground. The width of the girdling is generally 1-3 cm, which can be determined according to the strength of the tree. Generally, the tree is stronger and the width is relatively larger, and vice versa. This is not only conducive to promote plant flower bud differentiation, but also promote wound healing in time, if the wound has healed after catalysis, it should be carried out again, if the wound has not healed after the completion of catalysis, measures such as soil cultivation and application of healing agent should be carried out to speed up wound healing.

3. Root-cutting

In addition to girdling can inhibit the vegetative growth of the plant, the method of root cutting can also be adopted. According to the age and growth of the plant, in the first half of the month, at the edge of the crown 40-60 cm, a 20-30 cm circular trench is artificially dug to cut off part of the root system of the plant. However, this method is only suitable for strong plants, and weak plants are not suitable for use.

4. Shading

Shading can be used to reduce the temperature, which can reduce the light intensity and reduce the temperature by 4-9 degrees in the daytime. Shading can interfere with plant photosynthesis, reduce nutrient synthesis and promote flower bud differentiation. The shading net should have a shading rate of 90% Murray 95%, and if the crown leaves are dense, 60% should be used to achieve the ideal catalytic effect. The shading period should also be grasped, which should be considered in terms of leaf maturity and catalytic time, generally when the third tip of the plant is mature, and the number of shading days should also be determined according to the climate and catalysis date. In order to ensure fruit quality, shading days should not be too much. 35-45 days is appropriate.
