Nitrogen Controlled Phosphorus Planting watermelons should use less N fertilizer. If there are too many N fertilizers, more protein will be synthesized and more sugar will be consumed. Therefore, more organic fertilizer should be applied and phosphate fertilizer should be added appropriately. 300 kg of compost fertilizer per mu, 500 kg of pig dung, 400 kg of human waste and 80 to 100 kg of cake fertilizer, and 30 kg of phosphate fertilizer as basal fertilizer, or 30 kg of phosphate fertilizer deep in the roots of cucurbits at the beginning of the development of young melons. It can increase the sugar content of watermelon by 3~4 degrees. Spray sweetener Take 30 grams of borax, 5 grams of stevia, 5 grams of calcium chloride, add 50 kg of water and dissolve. After spraying in the seedling and flowering stages in the sunny afternoon, apply 40 kg water to increase the production 1~2. Into, sweeten 1.5 degrees. Suitable for sweetening fertilizer
Welding Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.
The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.
These flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection.
This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).
