When planting, where are the seedlings and fertilizers, and why? How much is appropriate? What fertilizer?

When newly planting saplings, after digging the tree hole, tear off the film at the grafting place when planting trees, and put the saplings on the left side of the hole, otherwise it will not be conducive to the later growth, and put multi-element compound fertilizer (multi-element grain compound fertilizer) on the right side, not less than 0.5 kg and not more than 1 kg.

The distance between the seedlings and the fertilizer in the hole is not less than 25 cm (isolated fertilization); After backfilling, compact the leveled land. In low-lying areas, the surrounding areas where trees are planted can be 20-30 cm above the ground to prepare for flood control. According to the degree of soil moisture,1-2kg of water can be poured under the trunk instead of fertilizer, which will not burn the roots and saplings, save labor and achieve the best effect. After planting the root water, immediately cover it with a black plastic film two feet square and flatten it.

Fertilization in late June, or multi-element compound fertilizer 1-2 kg, the distance between fertilizer and trunk is 30 cm, which is opposite to the last fertilization direction. In the future, it will be released once a year in March, June and September, and the amount of fertilization will be increased according to the age of the tree.

Extended data:

Seedlings are also called seedlings, the floorboard of all kinds of fruit tree seedlings, trees and shrubs. Sapling: A sapling with roots and stems. All saplings cultivated in the nursery, regardless of age, are called saplings before leaving the nursery.

When planting bare-rooted seedlings, the size of the tree pit must be determined according to the size of the root, neither too big nor too small. In order to ensure that the roots are fully stretched, it is advisable to dig holes.

When releasing seedlings, you must handle them gently, which will damage the root system. Put the saplings in the into the pit and stand upright so that the roots are 3? below the ground. When the soil reaches the root neck, lift the seedlings up by hand and shake them to combine the fine soil with the root system. After the seedlings are raised, step on the soil and return to the second layer of soil. When the soil is slightly higher than the ground, compact and step on it, and cover the ground with loose soil for the third time. The simple annotation is: the operation technology of "three burying, two steps and one seedling raising".

Irrigate 1 ~ 2 times immediately after planting the saplings, straighten the inverted saplings and level the planting area. Then, according to the growth characteristics of the seedlings, irrigation, intertillage weeding, topdressing, pest control, tillering and bud smearing are carried out.
