How to Improve the Survival Rate of Tea Seedlings After Replanting and Changing Varieties in Tea Gardens
How to Improve the Survival Rate of Tea Seedlings in Tea Gardens Being Replanted and Converted to New Varieties
1. Carry out soil disinfection. Before planting new tea seedlings in an old tea garden, apply an appropriate amount of mancozeb to disinfect the soil when preparing the land, so as to eliminate the toxins left in the soil by the old tea trees.
2. Establish a complete ditch system. The drainage and irrigation ditch system in the tea garden must be complete. The depth of the drainage ditches must exceed that of the planting ditches, and the drainage and irrigation ditches must connect with the planting ditches.
3. Dig planting ditches deep. To break up the original soil layer structure, the planting ditches should be dug to a depth of more than 60 cm. After the planting ditches are dug, first spread grass at the bottom of the ditches, then cover the grass with topsoil, and then apply organic fertilizer, applying the organic fertilizer at a depth of about 30 cm.
4. Plant at the right time. Autumn planting should be finished by October, and spring planting should be carried out in February. When introducing southern varieties to the north, it is advisable to choose cold-resistant varieties, and spring planting is better. Where the planting ditches are wide, a double-row triangular planting method may be used; where the planting ditches are somewhat narrow, single-row close planting is preferable. The basic number of seedlings per mu is more than 5,000 plants. After planting, water to settle the roots, spread grass between the rows, and top the tea seedlings at about 15 cm above the ground.
5. Strengthen the management of young tea gardens. First, promptly pull out newly emerged weeds; second, apply 1 application each of dilute human and livestock manure and urine in May and June; third, during high temperatures and drought, carry out sprinkler irrigation in the early morning or evening.
