How to improve the planting Survival rate of Fruit trees

The survival rate of fruit tree planting is the most important factor affecting the early rise and high yield of fruit trees. therefore, how to improve the survival rate of fruit tree planting is one of the knowledge that many fruit farmers most want to know. After a long period of practice and research, mastering good planting methods and effectively controlling pits, seedlings, planting and post-planting management can significantly improve the survival rate of planting. Here are nine specific planting methods:

First, arrange the root system.

After the fruit trees are dug up from the nursery, their roots have been harmed. In order to reduce the injured area, they should be sorted out. Use scissors to remove part of the main root, the large lateral root from the injury cut flat, do not oblique cut, the wound is easy to recover.

Second, arrange the branches and leaves

After the root system was dug off, it could not absorb enough water from the soil for aboveground branches and leaves to evaporate, and cut off 2 to 3 branches and leaves to reduce transpiration and improve the survival rate.

III. Timely planting

Spring planting should be carried out from soil thawing to seedling sprouting. Planting too early or too late is not conducive to seedling survival. Due to the characteristics of different tree species, the planting time should be different, peach, apricot, plum and so on should be early, red jujube should be late, and it is generally appropriate to plant immediately after soil freezing.

Fourth, select high-quality seedlings

The quality of seedlings is one of the important factors affecting the survival rate of colonization. Seedlings with high technical standards should be selected as far as possible, such as no diseases and insect pests, strong growth, well-developed roots, short internodes and so on. Before planting, we should carefully select seedlings, eliminate unqualified weak seedlings, growing seedlings, injured seedlings and so on, and carry out seedling arrangement.

5. Planting technology

One is to apply sufficient base fertilizer. In the planting hole, 1 kg of Leili seaweed fertilizer, 2 kg of Australian bacterial fertilizer and 0.2 kg of Aoli biological organic agent were applied in the planting hole, mixed well with the soil and then planted. The second is to soak the root in nutrient solution. Before transplanting, soaking the root system in the nutrient solution prepared with the proportion of 15ml, 25ml and 10L water for 30 minutes can promote the wound healing of the root system, accelerate the recovery of root growth and improve the survival rate. The third is to remove the film at the grafting interface. If the grafting film is not released, the lower and upper parts of the grafting interface will grow thicker, but the growth at the grafting interface is not synchronous, and it is easy to break from the grafting interface when the wind blows. The fourth is to straighten out the root system. When the seedlings are put into the planting hole, the root system should be flattened and stretched to ensure that the root system grows normally. Fifth, it is drenched with enough water. Put the seedlings into the planting hole, cover a thin layer of fine soil, pour enough Anzhu water to make the root soil connect closely, and then cover a layer of soil. Sixth, pay attention to the interface of marriage. When planting citrus fruit trees, the grafting interface should be exposed, while those of bayberry, plum, peach, chestnut and other fruit trees should not be exposed in order to grow and develop normally. Seventh, the tree plate is covered. After planting, cover the topsoil with rice straw, thatch, crop straw or pig and cow manure to maintain soil moisture and help to restore growth.

VI. Covering plastic film

After planting, the surrounding rake will be made into a shallow pot with the planting seedlings as the center, and the plastic film will be covered with 80Mel 100 square meters. It can effectively increase the ground temperature, resist drought and preserve soil moisture, and promote the early growth and growth of buds.

VII. fertilizer and water management

Watering fertilizer and water once on the 10th and 20th day after planting is the key to restore root growth. 10 days after planting, the root callus began to recover, and at this time, according to the ratio of 15 ml of Root Wang, 15 ml of Ji Keshan, 0.25 kg of high nitrogen flushing fertilizer and 50 L of water, 1 liter per litre of water could improve the root activity and shorten the slow seedling stage; 20 days after planting, according to the ratio of 0.25 kg of high nitrogen flushing fertilizer, 23 grams of 3% alexanil and 50 liters of water, 1 liter of water can promote the germination of new shoots. Up to August, 0.3% high nitrogen flushing fertilizer was applied once a month, and the survival rate of seedlings reached 95%.

VIII. Fixed drying

According to the cultivation requirements, 35 full buds were selected at the fixed dry height, and the cut was required to be smooth, non-splitting and treated with sealing agent or plastic film to prevent water loss and draining. In areas with frequent strong winds in spring, props should be set up to prevent the trees from wavering.

IX. Post-planting management

According to the management principle of "promoting ahead and controlling later", the newly planted seedlings should be irrigated in time according to the growth status of fruit trees and soil moisture, and fertilized in time, and at the same time, attention should be paid to the prevention and control of diseases and insect pests at the seedling stage. Create a good environmental condition for seedling growth as much as possible.

Combined with the above nine measures, when planting fruit trees, we should also consider the characteristics of local temperature and precipitation, timely watering, fertilization, weeding, and plastic film, so as to create a good growth environment for fruit trees according to the law of natural development, and take measures according to local conditions. Scientific management, in order to promote the healthy growth of fruit trees.
