The grapes are grown in greenhouses(1020 trays wholesale), so how do grapes in the greenhouse achieve high yields? Today, Xiaobian will take everyone to learn about the high-yielding points of grapes in greenhouses(square black plastic plant pots). Grape requirements from the beginning of warming to bud germination ≥ The effective accumulated temperature is 450 ° C ~ 500 ° C.

Generally, warming greenhouses begin to warm up from early December, and unheated greenhouses begin to warm up from early January(seed starting trays wholesale). Don't be too hurry, the indoor temperature rises too fast and too high, the temperature is suitable for the germination of grape bud eyes, and the ground temperature rises slowly(buy cheap plant pots), often causing uncoordinated development of the above-ground and below-ground, uneven germination, and poor flowering.(cheap plastic 3 gallon container suppliers in usa)


Therefore, in the first week when the curtain is warmed up(black plastic nursery pots), the temperature in the greenhouse during the day should be maintained at about 20 ° C, and at night, 10 ° C to 15 ° C, and then gradually increased to 25 ° C to 27 ° C during the day, and the maximum temperature should not exceed 30 ° C(15 gallon nursery pots for sale). At night, it should be maintained at 15 ° C. ℃ ~ 18 ℃. The humidity requirement is higher in this period, and the air humidity should be about 90%.


Grape germination to flowering period is the period from the beginning to the vigorous development of the main shoot of the grape(1 gallon nursery pots bulk), while the development of new shoots is stopped, and the ears are further differentiated. During this period, if the temperature and humidity are too high, new shoots of grapes will grow too long(plastic tray for hydroponics), which will affect the differentiation quality of the organs of the fruit, and then affect the subsequent fruit setting.


(cheap plastic 3 gallon container suppliers in usa)Moreover, high temperature and humidity during flowering will cause the occurrence of gray mold(5 gallon pot). The temperature during the day should be controlled between 25 ℃ ~ 28 ℃, the temperature should be around 15 ℃ at night, and the humidity should be around 60%(32 cell plug tray). Grape blooming, pollination and fertilization must be carried out at higher temperatures. Pollen has the highest germination rate at 27 ° C to 32 ° C.


When the temperature is lower than 25 ° C, it is easy to form most varieties with poor pollination, poor fertilization, and severe flower and fruit drop(seed starter trays). During this period, the temperature should be controlled between 28 ° C and 30 ° C during the day and 15 ° C to 18 ° C at night(72 cell seedling trays). Properly increasing the temperature is very beneficial to the increase of fruit particles, because the increase of fruit particles is important to stop at night.


Therefore, the water demand is large(plastic nursery pots), but the humidity is too low, the pistil stigma mucus is insufficient, and the development of the pollen tube is affected, which affects the fertilization process and causes flower and fruit drop. It is advisable to control the humidity at about 50% during this period(105 cell plug trays). After the grapes fall and settle, the young grape fruits enter a period of rapid expansion and development.(cheap plastic 3 gallon container suppliers in usa)


At this time, the temperature at night can be maintained at 18 ° C ~ 20 ° C, and the temperature can be controlled at 25 ° C ~ 28 ° C during the day(square nursery pots). During this period, the outside temperature and climate change drastically. When the indoor temperature exceeds 30 ° C, pay attention to ventilation and ventilation(garden pots suppliers). In the rapid expansion and development of young grape fruit, water should be irrigated about once a week.


(cheap plastic 3 gallon container suppliers in usa)After warming up for 30 to 40 days, The grapes started to sprout(plastic nursery pots wholesale). After irrigation, the humidity of the air will increase accordingly. Pay attention to disease prevention and control, and reduce the humidity of the air through ventilation to keep it at 50% ~ 60%(50 cell plug trays). Higher temperatures are necessary during this period, especially at night.
