First, jujube tree pruning principle and time Jujube tree pruning should be "mainly winter, combined with winter and summer; early Feng quality, reasonable load." The period of jujube tree pruning during winter is good from budding to the next year. Summer pruning can inhibit excessive growth of jujube head, reduce nutrient consumption, increase fruit set rate, and increase the yield and quality of jujube fruit. Second, jujube tree pruning method The pruning of the dwarf and dense planting of jujube trees should strictly implement the 16-character pruning principle of “pre-promoting post-control, plugging and putting down, wiping and twisting, and stretching and cuttingâ€. 1. Former to promote control In the early growth period (1-2 years) of the jujube tree, the rapid growth of the jujube tree is promoted to form the crown. After the control: When the crown is basically formed (3 years later) to take control of crown control measures to expand the crown, and promote its results. 2. Block and put down By means of measures such as retraction and topping, the height of the crown can be controlled. Generally, the height of the crown can be controlled to be about 2-2.5 meters. Put down: At the same time as jujube results, take a short cut and other measures to promote the emergence of new branches in the lower part of the jujube tree. 3. Branches In the shaping process of saplings, branches with smaller angles and suitable orientation are supported by wooden sticks to the ideal angle. 4. Pull the branches It is to use wire or rope to pull valuable branches to a certain angle and position. 5. Ring cutting One centimeter above the main bud, the trunk was scratched with a pair of scissors to reach the xylem to promote the germination of the main bud. 6. Bundling One centimeter above the main bud, bundle the trunk with iron wire, so that the wire penetrates into the phloem and reaches deep into the xylem. After the main bud is germinated, the wire is removed in time to prevent it from getting into the trunk or breaking the trunk. 7. wipe the bud The useless juvenile buds germinating on the jujube tree during the germination or growth period of the jujube tree can be wiped out several times a year, and are required to be erased with germination. 8. Topping When the jujube head grows to a certain length, the new top is removed, and the level of topping is determined by the growth intensity and size of the jujube head. Generally, the growth strength is strong and the heart is picked up. The growth potential is strong and the heart is lightened. The space is light and heavy and the hearts are picked up, leaving 5 to 7 The second branch, space Xiaoqiang to leave 2 -4 secondary branches. 9. Tune It is not yet fully lignified for the newly emerged azimuth angle, and it is bent and guided to the required space. 10. Twist If there is room for development, but the growth direction and angle are not ideal, the new shoots will be sprained from their bases by hand when they are semi-lignified, and the branches will be bent to the ideal orientation and angle. Corn is a good choice for consumption during weight loss because of its high available energy. The metabolic energy of maize is 14.06 MJ/kg, with the highest being 15.06 MJ/kg, the highest of the cereal feeds. This is mainly due to the fact that there is very little crude fibre in maize, only 2%, while the nitrogen-free leachate is up to 72% and the digestibility is up to 90%; on the one hand, maize has a high crude fat content, between 3.5% and 4.5%.
