The grapes sold in the market are large and round. In fact, the grapes have many small fruits, which are formed by the seed abortion. The mature small fruit seeds are all in the young stage, small and without kernels. So how do you prevent the grapes from producing small grains?
1. Manually remove the ear and remove 1/5 to 1/4 of the flower spike 2 to 3 days before flowering.
2. Management of fertilizer and water during flowering period, to ensure that there is sufficient nutrients in the “critical period of fruit setting nutrition†and “critical period of seed development nutrition†after the initial flowering.
3, regular pollination, in the initial flowering period to the full bloom period, spray 0.20% borax solution every 7 days, even spray 2-3 times, promote pollen tube germination, improve the rate of insemination.
4, summer cut pruning, in the beginning of the flower to the full bloom period, the results of the branch topping, while wiping off all the side shoots, leaving only one tip at the top, 7 days later, leaving the top tip of the 1-2 leaves topping, if germination again 2 secondary tips, wiped out in time.

Product Description
Detailed introduction: is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.
Formation of a protective layer
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.
4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2
400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.
FeS2→FeS + S
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).
(4)Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:
