Watermelon fertilization six bogey

First, avoid applying chlorine fertilizer. If watermelon is applied with chlorine fertilizer, it will reduce the quality of the fruit and affect the sugar content. Therefore, nitrogen fertilizer should be urea, ammonium sulfate, potassium fertilizer with potassium sulfate, grass ash is appropriate, it is not appropriate to apply ammonium chloride and potassium chloride and other chlorinated fertilizer. When using compound fertilizer, be sure to pay attention to whether “chlorine” is indicated on the product packaging bag. If “chlorine” is indicated, the application amount should be reduced as much as possible.
Second, avoid heavy application of concentrated fertilizer. When the soil is too dry, the fertilization concentration is too high, which will cause the root cytoplasmic aqueous solution to permeate outward, causing the cell wall to separate, causing the watermelon vines and leaves to lose water and withering until the plants die. Therefore, in the case of dry weather and low soil water content, irrigation or watering should be done first to moisten the soil before fertilization.
Third, avoid partial application of nitrogen fertilizer. If the watermelon is applied with nitrogen fertilizer, it is easy to cause a long length, affecting the fruit setting rate, reducing the number of melons and reducing the sugar content. In order to improve the yield and quality of watermelon, it is necessary to apply nitrogen, phosphorus and potassium fertilizers together, and apply organic fertilizers, such as livestock and poultry manure, cake fertilizer and grass ash.
Fourth, avoid fertilizing in rainy days. The rainy weather has high humidity and high soil water content. At this time, fertilization and fertilizer are not only easy to lose, but also the vine leaves are long and the leaves are crisp and easy to induce pests and diseases.
Fifth, avoid near-plant root fertilization. With the elongation of the melon, the root system will gradually expand. If the root is fertilized, the fertilizer will not be fully absorbed and utilized. Therefore, the fertilization should be applied to the distant part of the plant from near to far according to the elongation of the melon, in order to facilitate the absorption of the root of the watermelon.
Sixth, avoid the topsoil fertilization. In summer, the temperature is high, and there are many thunderstorms. If the fertilizer is applied to the topsoil, not only will the fat be easily evaporated, but it will be lost by the rain. Fertilization should be carried out in the deep roots between the plant roots, and then cover the soil to improve fertilizer efficiency.

Ball Valves

There are five general body styles of ball Valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve-especially the casing that contains the ball itself-are manufactured and assembled. The valve operation is the same in each case.

In addition, there are different styles related to the bore of the ball mechanism itself.

Ball valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
