A brief introduction to the planting and management techniques of the four seasons of carambola is as follows:
Water and fertilizer management: the application of fertilization in young trees is based on the principle of diligent application. Spraying foliar fertilizer in the growing season can transform the vegetative growth function of plants into reproductive function and inhibit the main shoots from becoming mad. Promote flower bud differentiation, more flowering, more fruit set, and promote development. As a result, the tree should be fertilized and the nutrient should be increased. Anti-falling flowers, fruit drop, cracked fruit, and deformed fruit make the fruit colorful, fruity and taste good. Note that irrigation should be done during the dry season and drainage during the rainy season. Plastic pruning: Four seasons of red carambola saplings are shaped to cultivate 3-5 main branches with uniform distribution, and a circular umbrella-shaped canopy with uniform distribution of lateral branches and firm structure is the main task. Carambola blooms 4 times a year, and its pruning period and method directly affect the flowering results. The first pruning is carried out around March each year, and the fruit is harvested 10-15 days after fertilization. The second time was held around June. The third time was carried out about 20 days before the cold dew. It is generally not appropriate to remove the branches of the canopy in the canopy, but keep the branches of about 2 cm as the result branches. Pay attention to the anti-corrosion film on the trimming mouth to promote wound healing. Field management: When the results are too much, in order to promote the fruit size, the fruit shape is beautiful, and the economic value is improved, the fruit should be thinned out, and the object is the deformed fruit, the young fruit, the diseased fruit. Pay attention to the wind; because the branches are thin and drooping, and the fruits are large and numerous, they are vulnerable to wind damage. During the typhoon season, bamboo branches are used to support the branches around the canopy. Main pest control: The main pests and diseases are anthracnose, red spot disease, bird feather moth, black leaf brown leaf moth and rubber scale insect. Must be prevented in time. Rotate a variety of targeted drugs to avoid drug resistance. A new high-fat film is added to the medicament to enhance the control effect.

The production and quality of enzyme preparations produced by plants are unstable due to the influence of growth area, season, climate, etc. The enzymes produced by animals are mainly extracted from the glands of slaughtered livestock, and the source is limited; only enzymes produced by microorganisms can meet the needs of any scale, with high yield and stable quality. Microbial enzyme preparations can not only replace the main types of animal and plant enzyme preparations with the same performance, but also produce high-temperature-amylases that act as catalysts at 100°C and detergent proteases that act at pH 10-12. In the 1940s, the microbial enzyme preparation industry developed rapidly. At present, the production of enzyme preparations is mainly based on deep fermentation, supplemented by semi-solid fermentation, and the ability of the strains to produce enzymes has also been greatly improved. The immobilized enzyme and immobilized cell technology developed in the 1960s and 1970s enabled the enzyme to be used repeatedly and continuously reacted, and its scope of application was also expanded. At present, in addition to the food and textile industries, microbial enzyme preparations are also used in daily chemistry, chemicals, pharmaceuticals, feed, papermaking, building materials, biochemistry, clinical analysis and other aspects, becoming an important sector of the fermentation industry.
