1. Pruning description of apricot trees: The branch and bud types and growth and fruiting habits of apricot trees are different from those of ordinary fruit trees. Therefore, the pruning of apricot trees is also unique: the fruit performance is stable, and the growth results are transformed quickly. After the jujube head is transformed into the jujube rootstock, it has strong ability to bear fruit continuously, small growth and easy to shape and prune; However, apricot trees are slow to respond to pruning, so they need to follow the trend and shape with branches; Pruning of apricot trees should be light, and pruning in winter and summer should be combined.
2. Precautions for Pruning: The branch and bud types and growth and fruiting habits of apricot trees are different from those of ordinary fruit trees, so Pruning of apricot trees also has its unique features: stable fruiting performance, rapid transformation of growth results, strong continuous fruiting ability, small growth and easy shaping and pruning after jujube heads are transformed into jujube rootstocks; However, apricot trees are slow to respond to pruning, so they need to follow the trend and shape with branches; Pruning of apricot trees should be light, and pruning in winter and summer should be combined.
3. The development law of apricot trees: The growth and development of four branches and two buds of apricot trees have certain laws, and the branches and buds are interdependent, mutually transformed, and there are also new and old relationships. The main bud is planted on the top of jujube head and jujube tree rootstock, or on the side between the axils of jujube head leaves. The jujube head and jujube tree rootstock formed after germination are not only different in growth, shape and function. Because of stimulating or changing nutritional conditions, jujube heads and stems can be transformed into each other.
4. Changing the growing branches into fruiting branches: after the jujube rootstock is stimulated, the jujube head can be extracted by pruning, and the fruiting branches are changed into growing branches; Early coring of jujube tree head can inhibit the growth of secondary branches, so that jujube tree head can be transformed from growing branches to fruiting branches, and the yield can be obtained in that year. The secondary branches on jujube head are formed by secondary buds, and the main buds between leaf axils can generate new jujube strands in the next year. The interdependence and mutual transformation between growing branches and fruiting branches are the basis of pruning and adjusting branch potential of apricot trees.
5. Pruning characteristics of apricot trees: Because apricot trees have a long life and few natural branches, young branches react slowly to pruning and are not easy to grow branches. Therefore, the pruning time of apricot trees is slower than that of their fruit trees, and it usually takes 7 ~ 8 years to finish pruning.
