Almost a month after the seeding of the saplings, the small sapling of the saplings appeared quietly from the soil, when we were to lift the grass over them and grow slowly after the sapling of the saplings, which took more than two months to grow to about 15 centimetres, and today we are going to introduce to you the techniques of sapling management. Sapling management techniques:..
The scavenger tree is grown and planted in the dens, then the soil is inserted and then the soil continues to be filled to the top of the cave, and a water trap is made around the scavengers and is presented today。
When planted, the sapling shall be watered immediately, and in the case of saplings with earthballs, the surrounding soil of the tree shall also be convulsed with iron or wooden rods so that the surroundings of the tree can fill the soil with water. Water should be pumped with care not to damage the earth's encircles, which must be filled with water so that the water can slowly be immersed in the planting grounds. In order to further increase the rate of growth, growth factors can be added to the water so as to stimulate new roots. The growth agent generally uses nitrous acid, which is dissolved with a small amount of alcohol and is then incorporated into the water, and is combined with a irrigation fluid at a concentration of 200 mg/kg, which is used as the first fixed root water。
Newly removed vanillas have been trimmed with two thirds of their crowns, with 90 per cent reduction in leaves and damage to the root system, which has a weak capacity to absorb moisture, so it is sufficient to keep the soil wet. If the soil is overwatered, it can significantly affect the air permeability of the soil. Instead, it inhibits the breathing of the root system, and if water is accumulated over a long period of time, it causes root decay, which seriously affects root growth。
Care should be taken in the planting process to maintain ventile drainage. However, the first should be thorough, and later carefully, depending on the weather, soil and soil quality, so that the principle of “no, no, no, no, no, no, no, no, no, no, no, no, no.” on the other hand, it is necessary to prevent the accumulation of water in the caves after the rains, i. E., to maintain a daily inspection of drainage and ventilation facilities, to detect congestion or water accumulation in a timely manner, and to ensure that the roots of the trees are free from water and dry. At temperatures below oc. Water spray should be stopped at the root of the earthball and normally humid on the leaves at noon, when conditions are ripe (the temperature rises back to above 5”c)。
This was the case, when the scavenger trees were planted, the first water was filled back with soil, and the trunk was covered with sackcloth, but not covered。
