First, improve the fruit set rate. 1 Refining organs. During the first 10 days of flowering, the sunny day at noon to release the wind, so that the floral organs as soon as possible to undergo training, to accept a certain amount of direct, improve the quality of flower buds. 2 spray fertilizer. 10 days before and after the flowering stage, spraying 0.3% urea with 0.3% borax or 600 times potassium dihydrogen phosphate solution, or spraying 5010-6 gibberellin or 300 times rare earth micro-fertilizer at full flowering stage. Clearly increase the rate of fruit set. 3 artificial pollination. Artificial pollination should be started in the early stage of cherry blossoms in the greenhouse and pollination should be continued 2 or 3 times. When the bouquet-like flowers are open, the pollinating tree flowers can be touched and touched with the hairpins. Pollen can also be collected manually and given with a brush or eraser. Pollination can be carried out from flowering to flowering on the 3rd day, but it is best for flowering on the same day. No matter what method is used to pollinate, it should be divided into two or three times in the early stage of flowering in order to ensure that the flowers in different flowering stages can be fully and timely pollinated. 4 Put the bees pollinating. The use of bees or wall bees to assist in pollination can increase the rate of fruit set by more than 20%. During the cherry blossom period, a box of bees can be set in each greenhouse. When pollinating with wall bees, the hive should be placed at 1 meter from the ground with 250 to 300 nests per nest. The length of the nest tube is 15 to 20 cm and the wall diameter is 5 to 6 mm. 5 new tips topping. About 10 days after flowering, it took a topping on the new shoots to prevent new shoots and young fruit from competing for nutrients, which also had a certain effect on improving the fruit setting rate.
Second, a reasonable load. In order to increase the single fruit weight of the shed cherry, improve the fruit's uniformity and fruit quality, the load of the tree body can be adjusted by means of sparse flower buds, sparse flower buds, sparse flowers and fruit thinning. 1 Sparse buds. Before budding, flower buds, usually a bouquet of 7 to 8 flower buds of short fruit branches can be sparse about 3 thin flower buds, retain full flower buds 4 to 5. 2 buds or thin flowers. Flower bud budding or sparse flowering after germination can play a role in saving nutrients and increasing fruit set rate, but should grasp the principles of sparse flowering, weak flowering, and sparse flowering. 3 thinning fruit. Usually after cherry physiological fruit drop. The degree of fruit thinning depends on the condition of the fruit set in the whole plant. Generally, a short fruit branch of a bouquet leaves 3 to 4 fruits, and a maximum of 4 to 5 fruits; the thinning fruit should be sparse, weak fruit, deformed fruit, and light is not easy to reach and color. Poor fruit; weak fruit-bearing fruit twigs with less than 5 leaves, generally should not retain fruit.
Third, promote fruit enlargement and coloring. 1 leaf spray fertilizer. Before dislocation after flowering, foliar spray of amino acid compound fertilizer or rare earth micro-fertilizer can significantly improve leaf quality, increase photosynthetic efficiency, and promote fruit red development and fruit weight. 2 pick leaves. After reasonable pruning and improvement of the conditions for ventilation and light transmission in the crown, the shaded leaves of the shaded fruits can be removed during the fruit coloring period. However, the degree of picking leaves should not be too heavy, so as not to affect the differentiation and development of flower buds. 3 laying reflective film. A retroreflective film is laid under the canopy 10 to 15 days before the fruit is harvested to increase light reflection under the canopy and promote fruit coloring. If the fruit coloring period is too late, consider removing the top film to improve light and promote coloration.
Fourth, prevent cracking fruit. 1 Stable soil moisture status. During the period from the hard nuclear stage of the cherry fruit in the greenhouse to the second rapid rate, the water content in the soil of 10-30 cm depth should be stabilized at about 12%. 2 Spray calcium salt before fruit harvest. Before fruit harvesting, spraying 0.3% calcium chloride solution, spraying once every 7 days, and even spraying 3 times, can increase the content of soluble solids in the fruit and reduce the cracking of the cherry fruit.
Fifth, pest control. Spray 1 to 2 times 1000 times 70% thiophanate-methyl in young fruit; after harvest, spray 1 to 2 times 500 to 600 times 70% mancozeb or 700 times 50% carbendazim; 7 to 8 months Spray 2 to 3 times 200 to 240 times the equivalent of Bordeaux fluid to prevent perforation, leaf spot and dry rot; flow gum disease in the early stages of the disease in the spot longitudinal slitting knife, squeeze juice, brushing stone Sulfur mixture solution. Caterpillars and moth-eaten pests are required to spray 20% fenvalerate 1500-2000 times or to use the habit of larvae of early-instar larvae to inspect the orchards in the period of 1 to 2 instar larvae, and then concentrate on killing.
All water based products have plenty of nutrients and water to support microbe growth under favorable conditions. Microbes invade water based products from multi-point sources, such as contaminated raw materials, poor plant hygiene, untreated water, and not properly preserved recycling materials. While adding in-can preservatives into the products should not excuse a factory from Good Manufacturing Hygiene Practices (GMHP), proper use of in-can preservatives coupled with GMHP can dramatically minimize the chance of microbial tolerance development, and assure unspoiled products to customers.Biocides formulators often use several types of in-can preservatives as active ingredients in their biocidal products for various industrial water based products. One of these active ingredients is benzisothiazolone (BIT). It has several distinct performance advantages, including good stability at high pH, good stability in the presence of reducing agents, and broad spectrum of activities against many microbes.
Sunshine Biotech supplies to all industrial biocides formulators with high quality BIT technical ingredients. Besides of BIT, we also provide its derivative, like BBIT, MBIT etc.
