Because the specific heat of water is large and the cooling is slow, the condensation heat is released when the water vapor condenses, which can increase the surface temperature(plastic plant trays wholesale). The contents include: irrigating, cultivating, weeding, cooling, top dressing, thinning seedlings, preventing diseases and insect pests, and seedlings overwintering in the seedling country(gallon pot). Non-sand land seedling circle with risk of wind erosion can also take the above measures.

According to the irrigation and frost prevention test, the temperature of the irrigated area is about 2℃ higher than that of the non-irrigated area(large plastic terracotta pots), and the effect of sprinkler irrigation is better than that of the ground irrigation source. Irrigation can not only prevent the need for freezing, but also prevent the early dryness of spring(162 cell seed starting trays). The emergence period of the sowing site ends, that is, the seedling stage, and the field management of the nursery site begins.
(best plastic cell seedling trays manufacturers thailand)When covered with plastic film, the film should be close to the bed surface, and the surrounding area should be compacted with soil(128 cell seedling trays wholesale). When the seedlings are unearthed, the film should be cut in the seedling section in time(200 cell seed starting trays). The size of the mouth should be based on the seedlings can expose the film, and it should be used immediately Wet soil compacts the emergence opening of the film to prevent damage to the seedlings at high temperatures.
Seeding and raising seedlings in sandy land, after sowing are often subject to wind erosion(cheap plastic plant pots bulk), sand hitting and other disasters, wind shields should be set around and in the middle of the seeding field to prevent wind erosion from covering the soil or sand hitting seedlings(15 cell trays bulk). When the monsoon stops, the seedlings have strengthened their resistance and can be divided into stages The windshield was removed in the section.(best plastic cell seedling trays manufacturers thailand)
Fifth, the emergence is even and tidy(128 cell plastic propagation tray wholesale price). One link is closely related to the quality of fungi and the yield of qualified seedlings. It is an indispensable condition for plant growth and development at all times. The current effective method is someone to supervise and drive with sound instruments(21 cell trays bulk). The branches, height, diameter and root growth of seedlings are formed by cell division, and the newly divided cells need water.
(best plastic cell seedling trays manufacturers thailand)If you can earnestly implement the requirements of scientific management in your work, you can cultivate high-quality and high-yielding seedlings(seed starting trays). Therefore, it can be considered that the field management period (to the seedling hardening period) with seedling land is the key period for cultivating high-quality, high-yield qualified seedlings(32 cell trays bulk). Water is the main component of plants. It is an important component for plants to form starch, protein and fat.
Soil moisture plays an important role in seed germination and seedling growth(square grow pots). The field management of nursery grounds is the work carried out during the year-round growth of seedlings. Seedlings cultivated in spring or cuttings are suitable for late frost when they first germinate(50 cell trays bulk). The seedlings are susceptible to frost damage. Before frost arrives, use sprinkler irrigation or surface irrigation to prevent Need to freeze the effect.(best plastic cell seedling trays manufacturers thailand)
If the soil is short of water and early images appear, the branches and leaves of the seedlings will turn yellow or even fall, and the growth will be slow or stop growing(plastic plant pots wholesale suppliers). When the root system absorbs mineral nutrients from the soil fill, the mineral elements must first be dissolved in water. The steaming effect of seedlings also requires water(98 cell trays bulk). Under the conditions of suitable moisture, the seedlings have many absorption roots.
