Second, deep turn the tree disk. The autumn fall time is appropriate from early October to late November. After the fall, we must break up the soil. The deep plowing can be carried out on a single plant. Digging an annular groove on the vertical edge of the canopy can also dig a ditch between the rows, with a depth of about 60 cm. Do not cut off the thick roots in the tree-pan, and topsoil and subsoil respectively. When filling back the soil, pick out the stones and mix the topsoil with rotten leaves, weeds or other farmhouse fertilizers and put them in the lower half of the ditch. The original subsoil is placed in the upper half of the ditch. In addition, the tree plate can be expanded according to the extension of the roots of the apricot tree. When the soil is insufficient, it can be supplemented by the earth outside the garden. Third, foliar spray fertilizer. In the middle and late September, two consecutive 0.2% to 0.4% urea solutions or 0.3% potassium dihydrogen phosphate solution were sprayed twice every 10 days to prevent premature leaf shedding and prolong the leaf growth period. Fourth, irrigation drainage. Autumn is the late period of vegetative growth. Reasonable irrigation is conducive to the manufacture and accumulation of nutrients and is conducive to the formation of flower buds. If the autumn drought is severe, it can be watered from August to September. Because the apricot tree is not resistant to pods, its roots can not be soaked for a long time, and it will be easy to injure the roots for a long time. When the autumn rain continues, if the apricot orchard has accumulated water, timely drainage should be taken to prevent apricot trees from feeling sick due to spasms. Fifth, weeding and weeding. Cultivated weeding is generally performed after watering in orchards. The cultivating depth is generally about 10 cm. Six, the amount of autumn cut. In the fall tube, the result is that the apricot tree is mainly sparse, and the pruning method that mainly involves large branches, low tree heights, and short cuts is used to promote new branches in the lower and inner tendon to form short fruit branches and bouquet-like fruit branches. For the leggy shoots that grow within the canopy, there must be twisting shoots, branching, and pulling branches for growth space to control vegetative growth and use more space. For those who do not have space for growth, mopping the branches, sick branches, and dense branches, they must be removed in time. Seven, control pests. 1 Protect the leaves. In the autumn, according to the hazards of diseases and insect pests, timely spraying of extermination and killing dicamba, dicofol, pyridoxine, tetromycin or carbendazim and other pesticides can be used to prevent insects and disease, protect the leaves, and increase the nutrition of the tree. accumulation. In addition, adding 3% urea solution is more beneficial to the tree. 2 Continue to prevent rot, smear with a rejuvenating agent or rot must be clear liquid. A Fetal Doppler, also called external fetal heartbeat monitoring System, is a handheld ultrasound device that uses soundwaves to listen to a fetal heartbeat. Normally, this checkup will start to detect your baby's heartbeat from around 8 to 10 weeks. This device looks for any increases or decreases in the baby`s heartbeat. It also checks how much the baby`s heart rate changes. The average fetal heart rate is between 110 and 160 bpm.

Apricot Autumn Fall Management
<p> First, autumn basal fertilizer. Autumn fertilization combined irrigation, cultivator and weeding, the time is set in early October. The production of trees depends on fertilization, that is, according to the age of trees, tree vigor, how much the result, soil conditions, etc. to determine the amount of fertilizer, but generally 1 kg of fruit to produce 1 to 2 kg of fertilizer is appropriate, fertilization to organic fertilizer-based. Fertilization depth is generally 40 to 60 cm. Using semi-circular grooves or radial grooves, alternating fertilization in the periphery of the crown. For apricot cultivars with different mature stages and different flower bud differentiation periods, fertilization at different times should be carried out. Early maturity apricot varieties should be fertilized in advance to ensure that the flower buds are full the following year and the tree has normal nutrient accumulation. In this way, the level of nutrients stored in the tree can be increased, the robustness of the apricot tree after harvest can be maintained, and flower bud differentiation can be promoted to ensure the output of the following year.
