Nursery has many advantages, such as centralized management, improving seed germination rate, preventing pests and diseases, selecting good quality seedlings for planting, ** good vegetable growth can bring a bumper harvest.
According to the efficacy of different vegetables, matching suitable LED growth lamp can shorten the time of seedling raising and growth, improve product quality and quality, and manage agriculture industrially to create more lucrative profits.
Sprouting and moving into the Wimbledon Room
During germination promotion, the degree of seed germination must be checked every day in the morning and afternoon before the radicle exceeds 0.5 cm, that is, before the epicotyls are exposed to the soil, stop germination, and move the hole tray into the greenhouse net planting bed as soon as possible to receive sunshine, so as to avoid prolonging the epicotyls in darkness and affecting the quality of seedlings.
Overcoming Seed Dormancy
Because some crops seeds have dormancy, they must break dormancy before germination. Seed dormancy can be divided into dormancy and embryo dormancy.
Cultivation and management techniques at Seedling Stage
The cultivation environment and management technology of seedlings are important factors affecting the quality of seedlings; good root system is necessary to improve the survival rate of transplantation after seedling cultivation, so the seedlings'robustness can be maintained at the root system development level. If only attention is paid to the growth of shoots and leaves above ground, it will easily lead to the growth of seedlings, which will have adverse effects on the field of planting. 。 The root system can be established quickly with appropriate water nutrient, light and temperature management. Therefore, the management techniques of water nutrient and various embryo control factors in seedling stage will affect the success or failure of hole tray seedling cultivation.
Facilities and Environmental Control
Climate change is severe, and rainstorms, monsoons, plum rains, typhoons and cold currents occur in all seasons. Therefore, seedling cultivation in cave trays should be carried out in facilities to protect young seedlings.
In the construction of facilities, the types, uses and economic factors of cultivated crops should be considered.
Shading lowers the temperature when the sun is too strong at noon and opens in the morning and afternoon to provide sufficient light.
Plant morphology is related to light. If plants grow in darkness after seed germination, they tend to form yellowing seedlings. Their epicotyls are slender and cotyledons are curled, and they cannot form chlorophyll. When plants receive light from each other, chlorophyll is formed, and the growth and development of vegetable slices are inhibited by light. Cangzhou plants Perpetual lamp, so the plant grows in the weak light internodes, hungry and long, and the internodes are shorter under strong light. Different light quality also affects plant stem growth. Red light with higher energy and shorter wavelength inhibits stem growth. Red light and far red light affect internode length.
