When the temperature in Wahne rises above 22 ° C(40 cell propagation trays wholesale), the air is gradually released from small to large to prevent the ambassador's seedlings from being blown by cold wind due to premature air release or excessive air release(seedling trays). During the nursery period, such as cloudy days, low temperatures, and weak sunlight, it is easy to cause cold roots, roots, and cataplexy due to low temperature and high humidity in the wane.

At this time, we must pay attention to cover the glass windows and grass curtains, but at the same time, we must pay attention to a short period of time to release the curtain and lower the temperature(50 cell seedling trays wholesale). Under the premise of heat preservation, try to open the grass curtain to make the seedlings get more scattered light, and strengthen the lighting conditions of the seedlings(v14 nursery pots). The pre-planting exercise is generally performed when the third true leaf is unfolded.(cheap rice seedling tray wholesale suppliers malaysia)
To achieve high yields of spring potatoes, the main technical measures are as follows: early maturing varieties are suitable for planting in the central and southern regions, but have poor disease resistance and low potential for high yield(51 cell propagation trays wholesale). At present, the medium-mature varieties with early tuber formation are commonly used. In the future, as the weather gradually gets warmer, the seedlings will grow up gradually, and the curtains must be gradually unveiled and postponed(plug plant trays).
After training, seedlings can improve the ability of cold and drought resistance to adapt to the open field environment after planting(104 cell propagation trays wholesale). It is basically similar to the management at the seedling stage, and gradually increase the amount of air release during the day, until finally the cover is removed(110mm plastic grow pots). It even caused the seedlings to die. Covers are gradually reduced at night, and when the minimum temperature at night stabilizes above 5 ° C, all covers can be removed.
(cheap rice seedling tray wholesale suppliers malaysia)The output is 5-6 times higher than the old local varieties in the past(128 cell plug trays supplier). In the past, the summer cucumber planting used old local varieties, and the yield per mu was only about 1,000 kg. In the early 1970s, the yield per mu of the "Jinyan No. 1" variety reached more than 5,000 kg(plastic terracotta pots wholesale). However, in recent years, the variety has started to degenerate, and its output has a downward trend; the current excellent variety to replace it is Xiafeng No. 1.
This shows that the variety is the internal cause of high yield(40 cell plug tray wholesale). At the same time, it also tells us that only by continuously purifying and rejuvenating the variety, selecting the best among the best, and constantly cultivating and introducing new fine varieties, can the high yield of summer cucumber be captured(seed cell trays). Relevant unit experiments showed that 5880 double-planted plants per mu increased the yield by 5% compared with 4410 single-planted plants per mu.
The composition of the yield per unit area of cucumber is the number of plants per mu multiplied by the number of single melons multiplied by the weight of single melons(2.5inch square nursery pots). 3 to 5 days before planting, the seedling bed is watered once, and the next day after watering, the soil will be raised with seedlings. Before sowing, you must first prepare the ground(128 cell trays). It can't be scattered when seedlings are raised, and can be planted after squatting in Yangwa for 2 ~ 3 days.(cheap rice seedling tray wholesale suppliers malaysia)
Therefore, under the premise of reasonable dense planting and ensuring the maximum growth of the group, all individual plants are fully illuminated, which is the second factor for high yield of cucumber(3.5inch square nursery pots). Therefore, the cultivation of summer cucumbers must choose fertile sandy loam soil and high dry land, and must have certain water conditions, so that it can be irrigated early and can be drained, with an average yield of 7150 kg per mu(12cm plastic grow pots).
