Four points for spring grape management
Spring is the season when the grapes sprout, leaf, head and flower. Strengthening the spring management of grapes is of great significance to improving the current year's yield and quality of grapes. This year's special weather, little snow in winter, grape spring management is critical. 1 Completely clean the garden and reduce the number of bacterial sources Comprehensively clean the orchard, bring the diseased branches, diseased leaves, and diseased fruits that were cut off during winter cutting to bring them out of the orchard to be burned or buried deeply, reducing the source of overwintering. When 10% of buds germinate to 1 cm, spraying more than 2000 times 2000 times 25% of propiconazole spraying, when the choice of fine weather without wind, and pay attention to washing spray. 2 Prime water as early as possible to ensure that buds are neat There is very little snow this winter and the soil is dry. In late February, as long as it is thawed, the conditional orchard should be filled with water in a timely manner to ensure that it is budding. Decomposed human feces and urine can be mixed with 0.2% urea before germination. 3 grape vines unearthed flat lay germination, wipe shoots tipping topping After the grape vines are unearthed, they should not be put on the shelves immediately, let them lie flat for 10 to 15 days, and the buds at the base of the vines will germinate. Then they will be put on the shelf again. Usually when one bud has germinated on one result, leave one bud every 15 centimeters. Each time the mother leaves 3 new shoots, the rest are erased from the base. When the buds are wiped, the apical buds or weak buds in the two buds are generally erased, and only 1 shoot is left in one bud. Then, the tip of the vine was affixed: Before the flowering of the preserved shoots, 5 leaves were picked up above the spikes, and 8 leaves were left without flowers. After topping, a large number of axillary shoots will be sprouted, leaving only 1 to 2 apical shoots on the top and leaving 2 leaves repeatedly to pick up the heart. The rest of the auxiliary shoots are wiped off. 4 spike treatment, boron spray calcium In order to ensure the fruit setting rate, the spike tip of 1/4 of the flowering spike is usually removed manually. The fluid boron fertilizer is applied during the flowering period—Boermei is 1000 times. After 5 days, artificial fruit thinning and spraying are performed for more fruit spikes. Shi Caiermei 1000 times, on the fruit calcium, and then bagging protection.
Primary Air Filters
Describe:
The primary filter is suitable for primary filter of air conditioning system, mainly used to filter dust particles above 5 μm. The primary filter has three styles: plate type, folding type, bag type, outer frame material has paper frame, aluminum frame, galvanized iron frame, Filter Material has non-woven cloth, nylon mesh, activated carbon filter material, metal hole mesh, etc. The protective net has double side spray plastic wire mesh and double side galvanized wire mesh.
Characteristics:
Low price, light weight, good versatility and compact structure,This efficiency filter, commonly used as a primary filter for air conditioning and ventilation systems, is also suitable for simple air conditioning and ventilation systems that require only one level of filtration.
Applications:
1. central air conditioning and centralized ventilation system prefiltration.
2. large air compressor prefiltration.
3. clean air return system.
4. local high efficiency filter prefiltration.
5. high temperature air filter, stainless steel frame, Summary of filtration efficiency of high temperature tolerance 250-300 ℃.
this efficiency filter, commonly used as a primary filter for air conditioning and ventilation systems, is also suitable for simple air conditioning and ventilation systems that require only one stage of filtration.
