First, change transplanting "plug seedlings" to "bag seedlings" In the past, the construction of cloned tea gardens mainly used “rooted seedlings†with roots and less soil. After transplanting, they were slow to return to green and had low survival rates. In recent years, it has been changed to "plug seedlings" (Fig. 1). Spring seedlings were cut and transplanted in the autumn. The seedlings were transplanted in the autumn and the survival rate was significantly increased because the tea seedlings could be transplanted with the roots. However, due to the short seedling age, small tea seedlings and weak anti-disaster ability, there are still different degrees of dead seedlings after planting. At the same time, after the tea plants are distributed and planted, the top-dressing management is more difficult, the growth rate is slower, and the shaping and pruning are also inconvenient. As a result, many farmers do not shape the pruning in time, which affects the shaping of the tea tree in the later period and the formation of the bonsai. If you use the “bag seedlings†cultivated in special nursery bags, these problems can be solved. There are several methods for growing bag nursery. The most reliable and practicable method is: tea growers prepare their own nutrient soil, and plug seedlings are planted in nursery bags. Then they are managed and cultivated in seedbeds for 1 year to make them grow into large seedlings. Then transplant to the new tea garden. The benefits of this law are many. One is that farmers themselves cultivate and can reduce costs; the second is to cultivate for one year in the local area, which is conducive to adapting tea plants to the local climate and environment, enhancing resilience, and at the same time solving the problem of transportation difficulties of large seedlings; It is focused on the cultivation of seedbeds, which will help strengthen the management of top-dressing, weed control, pest control, and disease prevention. It can prevent and prevent various disasters through measures such as covering and shading, creating a growth environment that is far better than Daejeon for the growth of tea plants, and promoting the rapidity of tea plants. Growth; Fourth, in the seedbed concentrated shaping pruning fast, convenient, is conducive to shaping a reasonable tree; Fifth, the roots of bag cultivation large seedlings developed, with more soil, strong adaptability, coupled with the roots of bags transplanting without damage, which can be greatly improved Transplanting survival rate of tea seedlings basically achieves transplanting of whole seedlings, and at the same time, the growth rate of tea seedlings after transplanting will also be significantly accelerated. Second, change the early stage of no fertilizer for deep base fertilizer, a small amount of multiple fertilizer In the past, the construction of clone tea gardens was limited by funds. Second, they were afraid of fertilizing and injuring young roots of tea. Therefore, the method of “white seeds coming out of the ground†was adopted. There was no previous application of base fertilizer or top dressing, resulting in lack of nutrients for tea plants. Slow growth. To speed up the growth rate of tea seedlings and achieve early gardening and early mining, fertilization must be carried out in the early stages. One must apply basic fertilizer. If the tea plantation is slotted, it can be combined with backfill and layered deep base fertilizer; if there is no time to extract the trough, the base fertilizer can be applied in the middle of the tea line, then the ridges can be filled with fertilizer, and the tea seedlings can be transplanted on both sides of the ridge. In general, more than 3,000 kg of long-lasting organic fertilizer is applied per 666.7 m2, and more than 75 kg of tea-specific fertilizer is used to uniformly mix soil and fertilizer. As long as the distance between the roots of the fertilizer and the tea seedlings is appropriate, it will not only do harm to the tea seedlings, but it can also promote the rapid growth of the tea seedlings in the early stage, and at the same time, it will lay a good foundation for the high-yield in the late tea garden. Second, timely fertilizer. In the past, using plug seedlings, the roots of the tea plants were weak when they were transplanted. However, after transplanting and survival, it is necessary to adopt “a small number of times, eat less and more meals†approach to top dressing, and gradually increase the concentration and dosage of fertilizer according to the growth of the tea seedlings. After using large bags of seedlings, we must pay attention to timely top dressing. In the early stage, foliar spray fertilizer may be used, or combined with watering, drought treatment, thin manure water, biogas slurry, urea aqueous solution, etc., and urea may be topdressed in shallow grooves on both sides of the tea line later. As long as the dosage is appropriate and the distance is appropriate, tea seedlings will not be damaged. Third, to open the cultivation of plastic film cover cultivation In the past, transplanted tea seedlings were generally cultivated in open field and were not covered with plastic film. The advantage of this method is that it is simple and labor-saving, but there are many problems: First, most tea plantations in clones are built in the second high mountain area (800 to 1 200 m above sea level) where the effective accumulated temperature is low in the year. The temperature rises slowly in early spring and falls in early autumn. Plastic film, tea growing time is limited each year, affecting the speed of the garden; Second, open field cultivation is afraid of drought, afraid of rainfall, but also afraid of frost damage, in case of continuous high temperature and drought will make tea severe drought, in case of continuous rainy weather will make the soil Humidity is too high. In case of heavy rain, it will make the soil harder. In case of low temperature, it will make the tea freeze easily. These are unfavorable to the survival and growth of the tea seedlings. Third, the uncovered tea seedlings are easy to grow weeds near the roots. If not, Weeding will affect the growth of tea seedlings. If weeding, it will easily affect or even damage the tea seedlings and affect the survival of tea seedlings. Transplanting tea leaves when covered with plastic film can better solve the above problems. First, the cover film can increase temperature and heat preservation. Early spring and late fall can effectively increase the soil temperature, promote the development of tea roots, prolong the growth time of tea seedlings, and increase the annual growth of tea seedlings. Second, the cover film can increase the drought tolerance and cold resistance of tea seedlings. And resistance to drought, the mulch film can play a role in maintaining drought and reduce the evaporation and loss of soil moisture in continuous drought; at low temperature, the mulch film can play a role in warming and heat preservation to reduce the damage of tea seedlings; when the rain or heavy rain persists, the mulch can play a role in shielding and keep. The soil moisture in the membrane is suitable, loose and air-permeable. In short, the cover film can make the soil temperature and humidity as appropriate as possible, and promote the rapid growth of tea seedlings. Third, the cover film can inhibit the growth of weeds near the roots of tea seedlings and create favorable conditions for the growth of tea seedlings. . Tea seedlings cover the film and can take a variety of ways. In the past, transplanted plug seedlings could be planted first or planted first. If transplanting bags to grow large seedlings, due to the large amount of stems and leaves on the ground, they can only be planted before planting. It is advisable to raise the mulch film in advance when the soil moisture is suitable, and then use a mechanical puncher to drill holes in the film surface. This is not only fast and efficient, but also ensures the quality of transplanting and improves the survival rate of the tea seedlings.
