Skills and matters needing attention of dipping vegetables in greenhouse

Vegetables cultivated in greenhouse often fail to pollinate normally due to lack of light and inappropriate temperature and humidity, resulting in serious flower and fruit drop, so plant hormones are often used to dip in flower yield in greenhouse vegetable production, which can increase fruit setting rate, accelerate fruit expansion and increase yield. But if the operation is improper, there will be deformities and reduced production, so how to dip vegetables in the greenhouse into flowers? Come and have a look with the editor.

1. Selection of dipping anther

The commonly used dipping anthers are 2mai 4murd and Fangluisu, which can be used in eggplant fruit vegetables. Studies have shown that the rate of fruit dipping is higher, but it will harm the buds and shoots of eggplant fruit vegetables to a certain extent, so it is generally used for dipping flowers or smearing; while the damage caused by anticonvulsant is mild, but the fruit setting rate is lower than that of 2mai 4rel D, so it is suitable for flower spraying. Therefore, the choice of dipping anther should be determined according to the plant growth, for the strong or weak plants, reduce the use of 2pyrryl D to dip in the flowers, while for the moderately growing plants, it is recommended to choose anti-falling hormone.

Second, the skill of dipping flowers

1. It is not appropriate to order flowers early.

Many farmers plant eggplant fruit vegetables very early, as long as there are flowers, often lead to poor flower bud differentiation in the first ear, and even after blooming, they will develop into deformed fruits in the later stage. Therefore, in the vegetable seedling stage should be for the purpose of cultivating strong trees, early flowers can also supply nutrients to the roots and stems and leaves, cultivate strong seedlings, but pay attention to a degree.

2. Don't dip too many flowers.

The number of dipping flowers should be determined according to the plant growth, if the plant growth is weak, should be less dipped in flowers, first raise the stem vine, inhibit the reproductive growth of the plant, resulting in leaf dysplasia, resulting in multiple diseases and insect pests.

3. Experiment on the change of medicament first

Dipping in anther preparation is also very critical, if you want to change the formula, it is very easy to cause fruit deformities, dipping anthers do not add foliar fertilizer containing hormones at will, and change the concentration of the agent in the case of different temperature, but the experiment should be carried out first. only use it in a large area after the experiment is successful, so as not to cause huge losses.

Third, matters needing attention in dipping flowers

In dipping flowers is to pay attention to time, generally in the first ear flower blooming 2-3 flowers can start to point flowers, dipped flowers too early easy to form stiff fruit, too late easy to cause fruit cracking. When dipping flowers, you should be careful not to drop the price medicine on the branches and leaves, which is very easy to cause drug damage, resulting in wilting and necrosis of the damaged parts. Dip in the flower do not point the stigma, it will stimulate the stigma to crack fruit, especially when the repeated flowers are serious, it will almost cause no harvest. Also pay attention to soil moisture, if the soil is too dry, should be watered first and then dipped in flowers, to avoid the phenomenon of fruit cracking caused by watering after dipping flowers.
