How to manage grapes before and after flowering?

There are probably three reasons why orchid roots become soft. One may be because of too much watering, orchids on the water demand is not very large, if more than its normal demand, then it will form water on the root impact, need to take off the pot as soon as possible to cut the bad roots, and then disinfection and re-planting. Secondly, it may be because of too little water, which will make the roots of the plants soft because of dehydration, and need to replenish water in time. Third, it may be caused by excessive fertilization and excessive nutrition, and it is necessary to wash the soil with water to discharge fertilizer.

1. Appropriate topdressing

It consumes more nutrients in the flowering period, in order to meet the needs of flowering and fruiting, topdressing treatment should be carried out before and after flowering.In addition, boric acid should be sprayed before flowering, which can improve fruit setting rate.In order to reduce the consumption of nutrients, but also in time for pinching, pinching ear tip, picking shoots and other work.

2. Control of temperature and humidity

It prefers a relatively warm environment, preferably around 28 degrees during the day and 16-18 degrees at night during the flowering period, which can promote better flowering.After blooming, the humidity should be well controlled, and watering should be stopped first, and the humidity should be about 50%.Greenhouse cultivation should also be ventilated regularly, open-air cultivation should loosen the soil and take measures to reduce humidity.

Third, sparse inflorescence

Thinning of inflorescences should be carried out according to the growth strength of branches, from 10 days before flowering to flowering period.There are more than two inflorescences on each fruit branch, and the thin and weak inflorescences are thinned out, so that the strong fruit branch has 1-2 inflorescence, the medium and strong branch has 1 inflorescence, and the weak and small fruit branch does not need to keep inflorscence.

4. Artificial pollination

Although there are many varieties, most of them are hermaphrodite flowers, which can be fertilized naturally.However, some stamens will degenerate early, pollination is needed to ensure yield, so artificial pollination should be carried out in time.
