The management of Zanthoxylum bungeanum fruits after picking and picking is one of the main techniques in the cultivation of Zanthoxylum bungeanum. The production is often due to improper picking methods and overly simple and extensive tree management after picking, resulting in damage to branches and branches and reduced accumulation of nutrients. Flower bud differentiation and flowering results by the next year. According to the biological characteristics of pepper and pepper farmers for many years of production practices, when picking pepper must do the following:
First, timely picking:
(1) The fruit ripening period of Zanthoxylum bungeanum is affected greatly by species, climate, and region. It is difficult to determine the ripening stage. Due to the differences in species, ecology, management level, and maturity stage, the harvest period is generally July to September. The main area of ​​our district is Nine Leaf Green Pepper, which is generally from late June to the end of August.
(B) Mature external features: When the pepper leaf surface appears shiny and shiny, the fruit color becomes red or purple, the skin of the fruit-like protrusion of the oil is obvious, transparent and shiny, the seed is black, the skin is easy to crack, strong flavor When you are spicy, choose sunny picking.
(3) Harvesting methods: According to the characteristics and uses of the varieties, determine the harvesting time, select the harvest on a sunny day, pick the whole ears for harvesting, and carefully cut off the handles with scissors or cut the handles with scissors. Do not pinch the peppers by hand. Grain picking, so as not to break down the oil cells on the fruit of Zanthoxylum bungeanum to reduce its color, aroma, taste and other qualities, affecting economic value. After picking it, place it gently in the basket. At the same time, the peppers in the basket should not be packed too much, so as not to crush and collide, causing the oil cells on the peel to break and affect the quality.
(4) Precautions for harvesting: First, to protect the branches and branches, the most prominent feature of the peppercorns is their ability to continuously produce fruiting results. The middle and long fruiting branches are basically at the top of the fruiting branches. If they are cut with scissors, they are easily cut off during harvesting. The panicle axis of the flower affects the regeneration of new spikes. The correct approach is to hold the fruit branch in one hand, to grab the ear from the base of the fruit branch in one hand, and to try to maintain the total axis of the flower spike. The second is to protect the leaves. After the pepper is harvested, the nutrients produced by the leaves are all turned to nutrient accumulation. After picking peppers and before the wintering (at the end of October), the leaves are kept as intact as possible, with thick greens, enhanced photosynthesis and accumulation of nutrients.
Second, pay close attention to drying, drying a great impact on the value of pepper products, is the key to high quality and price. Should do the following: First, picking should choose the eye-catching weather, avoid rain or bring dew harvest; Second, the mining side of the sun, harvested in the morning, noon, afternoon drying for the day to dry, when the sun does not dry Stall in the house, do not pile up, otherwise it will increase the strength of respiration easy to mold; Third, must dry the mattress to dry, and use wooden sticks to support ventilation and ventilation; Fourth, drying is not too thick, about 3 cm, the most appropriate, Every 0.5 to 1 hour is used to stir the bamboos once; Fifth, do not expose directly to the cement floor. This will easily burn the seeds and affect the seedling rate and the oil yield. Sixthly, in case of rainy weather during harvest, it must be fruited. Open the doors and windows, open the doors and windows, diligently diligently dry, pay attention to ventilation, if necessary, can be used to bake; seven is the current, pepper drying machine, has been used in production, basically eliminating the harm caused by rainy weather.
Third, comprehensive post-harvest management:
(i) Drought protection and tree maintenance. Soil moisture content is low, the soil layer is thin and the soil blocks should be moisturized on sunny mornings. It is better to cover the crop draft stalk.
(b) exert post-natal fat. After harvesting, 5 to 10 kg of livestock manure per plant were applied, and 25 to 50 g of superphosphate and 10 to 25 g of potassium sulfate were added.
(c) Pruning. The pruning of prickly ash is different depending on the species and age of the tree. The juvenile tree should be dominated by sparse shear, which will rapidly enlarge the crown formation. At the same time, it is appropriate to leave more twigs as an auxiliary branch and fruiting branch to benefit early results and more results. For strong branches, do not cut; for weaker branches, cut short to promote strong branches. Short cut should be light should not be heavy, generally cut the branches of 1/3 or 1/4; general growth of a robust tree, pruning should be light; growth weakness, excessive results, pruning should be heavy; with large and small phenomena of the pepper Park, the year should be re-sheared fruit branches, leaving more branches or promote development and development branches; young years should be more than the results of branches, appropriate removal of some of the development of branches, all the size of the phenomenon of serious Jiaoyuan, if the use of the above methods of pruning, Coupled with other agricultural technical measures, it will be able to solve the phenomenon of age and size in 3 to 5 years.
