2. When transplanting seedlings, dig deep and shallow seeds in the planting ditch. Before planting, prune the root system of seedlings and cut off the root at 20 cm to promote the growth of new roots. After planting, return the soil and raise seedlings at the same time, and then pour water steadily. After the water has completely penetrated, cover the soil with plastic film. The joint should be 65,438+00 cm above the ground. When planting, the seedlings will be inclined 30 degrees in the same direction, which is convenient for taking off the shelf to prevent cold all the year round.
3. Management of seedling stage After planting, management should be carried out according to the period, such as accelerating germination, shaping and pruning, wiping bud pruning, flower and fruit management, fertilizer and water operation, etc. There are two main kinds of vines that can be left in trellis cultivation. As long as 1 bud is produced, it is necessary to pick the core to promote more germination, leaving the two most flourishing branches as the main vines. When the main vine grows to 1.20cm, the secondary branches under the iron wire can remain 1 bud, and the secondary branches on the iron wire can be cored in three ways, namely, 3, 3 and 4, which can quickly form a two-year yield.
4. Pruning management Sunshine roses are suitable for pruning in combination with short branches and middle branches, with 2 buds for short branches and 3 ~ 4 buds for middle branches, ensuring 5 ears per vine. Double-branch regeneration was used to avoid the outward migration of the result site.
5. Water and fertilizer management In order to make the planted plants grow rapidly, nitrogen fertilizer can be dissolved in water before application. In addition, topdressing should be carried out many times a year, the first time is in spring, which is the growth period of plant roots, so topdressing should use nitrogen and phosphorus fertilizers, and topdressing can be done by pouring or drip irrigation; The second fertilization is also applied by watering or drip irrigation during the growth period of branches and leaves. One acre of land can use 2-3 kilograms of high-nitrogen compound fertilizer once every half month for 4-5 times in a row, so as to improve the quality and yield of fruits when they are ripe. Phosphorus and potassium fertilizer can be topdressing, and topdressing 2-3 kilograms of potassium fertilizer on an acre of land can significantly increase the yield. Base fertilizer should be applied before defoliation after harvest to improve the quality of flower buds.
6. Pest control is an unfavorable factor affecting the healthy growth of Sunshine Rose Grape. It is necessary to combine prevention with control, give priority to prevention and comprehensively manage it. Agricultural control measures can be taken, and the harm rate of black pox and frostbite can be reduced by using appropriate chemicals.
