Site selection is divided into two, respectively, is the selection of pre-seedling and planting site selection, pre-seedling will usually be in the soil layer is relatively loose and the landscape is flat, drainage pipe irrigation excellent, close to the drinking water source belt sand or soil to carry out the sowing of pre-seedling, planting site must be only abundant water resources, the soil layer is rich and fertile,
Contains soil organic matter colorful, the soil layer is not very sticky soil can be planted, in the case of turning the land, the soil layer to the soil layer is not big. The clay is not big soil can be planted, in the case of turning over the soil layer of the seedling land should be fine, flat, planting land can choose to full reclamation or hole reclamation, but must play a good bottom fertilizer, the base fertilizer is mainly organic fertilizer or agricultural fertilizer as the leading, and then according to the characteristics of the soil to fill in the other micronutrient fertilizers.
2, sowing pre-seedlingBefore sowing must be put into the seed in the river sand to carry out the hidden storage of teeth, preferably in the house to carry out, and to carry out the closed windows and doors in the house, at the same time to do a good job of disinfection and sterilization, in order to prevent the harm of the pine tree buds efficiently, usually must be in the winter of the first year of the seed to do a good job of teeth, the second year of the spring to carry out the sowing, the sowing of the seedling to carry out the time Sterilization solution,
Subsequent to the selection of strip sowing in the form of proportionality of the seeds scattered, covered with a layer of plastic film or rice poles and other insulation for heat preservation, pre-seedling all the items applied must be carried out sterilization. After sowing, we should pay attention to the water management method in the seedling period, moderate watering, generally one month after sowing, we can sprout, during this time we have to avoid rats or birds of prey on the seedling injury,
Can be sprinkled on the field with some of the liquid bait, and every seven to ten days with triazolone or ferrous nitrate to carry out the sprinkling, so that you can improve the immunity of the seedling, at the same time, can also prevent pests and diseases, and at the same time, can also be a good way to avoid the damage to the seedlings. Also be able to prevent pests and diseases, and then in the growth of seedlings in the course of the soil must be done many times hoeing, which can promote the growth and development of seedlings, and finally when the seedlings grow to less than ten centimeters can be carried out in the case of transplanting.
4, reasonable dense plantingBecause the pine tree to undergo a number of transplanting to grow trees, so the relative density of each transplanting is a certain difference, in the case of the first transplanting basically line as long as in accordance with the rows of thirty to forty centimeters per row, each thirty centimeters of the spacing to carry out the planting can be, and the second process is generally in accordance with the rows of sixty centimeters, fifty centimeters of planting, third transplantation is generally a line of one meter, the planting of fifty centimeters to carry out the planting. The third transplanting is generally rows of one meter five, plant one meter to carry out transplanting, each time a moderate increase in the interval, the last spacing to maintain the rows of four meters to five meters, plant three meters to four meters spacing to carry out transplanting.
5. Pine nut seedling managementAfter sowing, we should pay attention to the water management methods in the seedling period, the moderate implementation of watering, generally 30 days after sowing almost sleep buds, during this time we have to prevent rats or birds of prey on the seedling injury can be sprinkled on some of the fish bait with medicinal liquid in the field, and every seven to ten days to implement the spraying of triadimefon or ferrous nitrate, so that you can This will improve the immunity of the seedlings and prevent pests and diseases at the same time. The following in the growth of seedlings in the course of the implementation of a number of hoeing, turning the soil, which can promote the growth and development of seedlings, and finally wait for the seedlings to grow to less than ten centimeters can be implemented in the case of transplantation.
