Nursery skills and precautions after the fall
The next season after the autumn is winter. This is the key moment for the maintenance of seedlings. If the management is not proper, the seedlings will be frozen and lead to death in the winter. How do we maintain the seedlings after the autumn? Timely irrigation The seedlings in the fast-growing period need to adopt a large number of methods. And each irrigation should be filled, and be careful not to wash the seedlings, to prevent damage to the stems and seedlings. If the seedlings do not leave before winter, be sure to pour the winter water. Clear weeds The nursery base is the peak of weed growth in autumn, so it is necessary to remove weeds in time, and combine the weeding to carry out the tree hole loose soil. When cultivating, you should pay attention not to hurt the seedlings, not to crush the seedlings. For cuttings of broad-leaved trees, it is necessary to control the lateral roots of the broad-leaved trees, and pick them up and remove them in time. Flood prevention There are more rains in autumn, and once the seedlings are affected, the impact on the seedlings will be great. So you have to dig the drain. Do well in flood control measures. Fertilization is generally applied to quick-acting fertilizers such as urea. The method is to ditch between the rows, apply the fertilizer to the ditch, and cover the soil. The fertilizer can also be diluted and sprayed evenly on the seedbed (ridge, hoe), and then rinsed with water. Under normal circumstances, apply urea from 15 kg to 20 kg per acre, apply it again after 15 days, and apply it two or three times. Top dressing In the fall, spray 0.2% urea plus 0.3% potassium dihydrogen phosphate solution. Broad-leaved tree species are best not to be fertilized after the beginning of autumn, in order to prevent seedlings from growing. Control side root For broad-leaved cuttings, it is necessary to control the side roots of the leaves, and pick them up and remove them in time. Disease prevention and control Nursery land should do a good job in predicting and forecasting pests and diseases, which can effectively prevent possible pests and diseases, and timely prevent and control the occurrence of pests and diseases. It can be sprayed with a high concentration of strong deodorant 500 times to 600 times. In high temperature and high humidity weather, it is easy to cause pests and diseases. Therefore, according to the growth of seedlings, it is necessary to prevent possible pests and diseases, and timely control of existing pests and diseases.
