For tray seedling seedlings, tray substrate seedlings are a major technological innovation in vegetable seedlings(32 cell propagation trays wholesale), overcoming the drawbacks of traditional nutrient seedlings with low seedling rate, difficult to control seedlings, high cost, and large bed area. Welcomed by the majority of vegetable farmers. In the face of high temperature environmental conditions in summer, it is necessary to cultivate the following five links in order to cultivate a uniform and uniform seedling(wholesale nursery pots). The choice of the tray should be determined according to the type of vegetables and the size of the seedlings.

(cheap plastic plant trays wholesale supplier)According to the seedling age and transplanting period(50 cell propagation trays wholesale), more than 50 holes are used for grafting seedlings. Before seeding, the tray should be disinfected first, and the tray can be soaked with the solution of the mildew solution. It can also be disinfected with potassium permanganate solution, especially the old tray. The choice of matrix is an important link in the seedling substrate seedling cultivation(plastic nursery pots manufacturers). Many seedling factories and vegetable growers in production are caused by the slow selection of the seedlings and the yellow leaves.
For example, more than 72 points or 105 points are used for sweet peppers, and 105 points are used for tomatoes(72 cell propagation trays wholesale). The selection of the substrate should be based on the pH value and nutrient requirements of the roots of the melon seedlings, and the appropriate substrate should be selected. Luqing seedling substrate and so on. And the substrate should be disinfected before being placed in the plug tray(plug trays wholesale), or mixed with the antibacterial 968 Miaobao in a certain proportion, and the biological bacteria can be used to protect the normal growth of the seedlings by the action of bacteria and bacteria to ensure the transplanting of the mature seedlings.
(cheap plastic plant trays wholesale supplier)It can be treated with carbendazim, spray the bottom water once before sowing, and pour through the substrate(98 cell propagation trays wholesale). When the bottom layer starts to see water, it can meet the requirements of sowing and germination, and at the same time, it can be combined with water spray according to the disease at seedling stage. If the bottom water is too much, the bed temperature will be lowered. If the bottom water is insufficient, it will increase the difficulty of hydrating and promoting the whole seedling. After sowing, according to the requirements of the depth of different crops(black plastic nursery pots), the substrate should be covered with the substrate, and then covered with the film to keep warm and moisturize, and promote the seedlings, the whole seedlings and the uniform seedlings.
Reasonable determination of suitable sowing date(105 cell propagation trays wholesale), prevention of high temperature and lack of water to burn seedlings during emergence, in order to conserve seedlings and promote seedlings. Although the seedling substrate seedlings are simple and feasible, in the hot and rainy season in summer, the use of "two nets and one membrane" to cover seedlings is still the focus of management during this period. Two nets, namely a sunshade net and an insect net; a film, that is, a plastic film. The sunshade net can play the role of shading and cooling(plastic nursery pots wholesale), and the insect net can prevent the insects from sneaking into the body, and the film can play the role of rain prevention.
(cheap plastic plant trays wholesale supplier)When the seedling emergence rate of the seedlings reaches 50% or more, the mulch film should be removed in time(128 cell propagation trays wholesale). It should be emphasized that the use of the sunshade net must be scientific and reasonable, and the seeds should not be covered for a long time after emergence, so as to avoid poor growth of the seedlings. Pot seedlings should pay attention to timely hydration, and generally need to replenish water when the surface of the substrate is whitish. At the same time, according to the content of nutrients in the substrate and the growth of the seedlings(plastic nursery pots), most of them adopt the method of foliar spray fertilizer, combined with hydration to properly supplement the nutrition.
