The traditional jujube garden management is more extensive, generally does not carry on the summer cut, thus causes the tree shape to disorder, the backbone branch angle is small, although the tree body is tall, but the ventilation is poor, the light output is low. Jujube summer cut not only favorable ventilation and light, but also can adjust the tree nutrition, improve the fruit setting rate, improve the quality of fresh dates. When summer shear jujube summer cut should be carried out when the jujube head grows slowly, generally in mid-June. Premature secondary shoots and jujube stocks tend to germinate new branches and affect fruit setting. Too late, overgrowth of nutrients will consume tree nutrients. The South is not conducive to the outcome of the second. How to summer cut jujube summer shear should be based on thinning, and the combination of thinning and cutting. Jujube tree pruning should master the following principles: "Extension of backbone branches, short weaknesses, weak branches, cultivation of robust branches, use of long branches". Thinning and sparse removal of bad branches and densely squeezed shoots and leggy branches. A new jujube head may be left every 50 centimeters to cultivate the result branches, which is conducive to secondary fruiting. The long shoots will be updated, retracted, and the new shoots sprouted under the short cuts of the branches will be picked and left. The long and strong new jujube heads will be placed in long positions and will not be pruned so that the main branch can be extended to the branches and lateral branches to expand the crown. , add more results to the site. Wiping buds sprouted on the main trunk and shoots sprouted. Topping the heart is to cut away the buds on the top of the jujube head to control its growth, promote secondary branches, and increase the number of jujube stocks. The degree of picking can be determined according to the orientation of the branches. A large space can leave 5~6 secondary branches, a small space can leave 3~4 secondary branches, to increase the results of branches, the results of the year, and even create secondary fruit conditions. If the use of an imperishable branch has a biased crown tree, a missing branch, or a space for growth, it can pull the long branch out of the internal bandits, fill up the space, and enlarge the result area. Amino Acids are biologically important organic compounds composed of amine and carboxylic acid functional groups, along with a side-chain specific to each amino acid. With biological significance, amino acids are important in nutrition and are commonly used in Nutritional Supplements, fertilizers, and food technology. Industrial uses include the production of drugs, biodegradable plastics, and chiral catalysts.
