Seedling raising technique of short-spike cuttage of tea plant

First, the selection of mother trees and the cultivation of cuttings: the vigorous growth, the same characters of improved varieties, and the disease-free garden were selected as the mother garden, and then the mother trees were selected in the mother garden, and the selected mother trees did not pick tea, but left shoots to cultivate cuttings, generally leaving spring shoots as summer cuttings, summer and autumn shoots as autumn and winter cuttings, and topping about 13 days before cutting.

Second, nursery land selection and management: select areas close to the new planting garden, convenient transportation, loose and fertile soil slightly acidic red-yellow loam, convenient drainage and irrigation. Ploughing and tanning, raking and smashing, removing grass roots, tree roots, sundries, etc. According to the width of the border is 1 meter, the width of the furrow is 50 cm, the depth of the furrow is 15 cm, the ditch is opened in the east-west direction, the drainage ditch is opened around the field, and the border surface is fertilized with bottom fertilizer, and the rotten manure is applied to 60 kilograms per mu, and calcium superphosphate is 30 to 50 kg, which is evenly mixed with the bed soil, and then spread yellow and red soil on the border surface, 5 colors 6 cm thick.

Third, the selection and cutting of cuttings: choose disease-free insects, wood or semi-wood, full axillary buds, yellow-green and purple-hardened branches. When cutting from top to bottom, starting from a hard section, 3 cm per panicle, with a complete leaf, a full axillary bud, the upper and lower cutting mouth is smooth, parallel to the growth of the leaf, if a node is less than 3 cm, the next leaf can be removed with two nodes and one ear.

Fourth, insertion method: it can be inserted all the year round, the petiole of axillary bud is inserted into the soil at an angle of 65 degrees with thumb index finger, the axillary bud of petiole is exposed to the soil surface, the row spacing is 3 cm, and the leaves do not overlap. First drench in water and then build a shed for shade.

5. Field management: insert and send new roots (it usually lasts 90 days). It is necessary to drench water frequently, shade carefully, keep soil moisture capacity 60%, sprinkle water once in the morning or evening, and do not root or rot if it is too wet. Send new roots to seedling height of 10 cm. Apply fertilizer frequently and thinly, using 1.5 MUR 2 kg of urea per mu. Use your hands to pick weeds or buds, carefully loosen the soil to prevent root damage, and gradually reduce shading. The seedling is 10 cm high to come out of the nursery. Increase the amount of fertilizer application, strengthen the control of diseases, pests and termites, open the shed to refine seedlings, cut the top one month before leaving the nursery, and drench through water before coming out of the nursery.
