ICESUN tempered vacuum glass once won the second-glass certification of integration and innovation of science and technology competition. The impact and bending strength of vacuum glass is much higher than that of ordinary glass. When the glass is damaged by external force, the fragments will form small obtuse angle particles similar to honeycomb, which is not easy to cause serious harm to human body. Tempered vacuum glass has good thermal insulation performance, with a minimum heat transfer coefficient of 0.19w (m2 * k). For vacuum glass with palm thickness, its thermal insulation performance has exceeded that of brick wall with 1m thickness. High-tech Vacuum Glass can be safely used in different harsh environments all over the world, and has become a real super environmental vacuum glass. In virtue of the super performance on thermal insulation, resistance to grade 9 wind pressure and sound insulation, our Safety Vacuum Glass products have won many praises at home and abroad.

1. Potato science cutting potato method:
(1) Small potatoes below 40g can be sown with whole potatoes.
(2) 51g-100g of potato tubers, can be two longitudinally.
(3) 100g-150g potato chips, all three open longitudinal oblique cutting method, that is, the potato chips are cut longitudinally three times.
(4) Potato chips of 150g or more, from the tail of the tuber, according to the number of bud eyes, according to the arrangement of the potato buds, several small potato husks of small triangles are formed, and each small triangle potato stalk preferably has more than two healthy bud eyes.
Pay attention to the top advantage when cutting the block, try to bring the top bud. The cut should be placed near the bud eye to facilitate rooting.
2, potato cut size: cut seed potatoes weighing 35 ~ 40g, each cut with 2 sound buds.
3, potato cutting time: generally 2 to 3 days before sowing, it is not appropriate to prematurely cut, to prevent the length of seedlings or water loss.
4, chemical dressing: use 2 kg of 70% methyl thiophanate plus 1 kg of 72% agricultural streptomycin and evenly mix 50 kg of talcum powder into a powder, requiring 30 minutes after the potato is cut. The seed dressing treatment is carried out, and the amount of the powder to be mixed is 50 kg of the cut potato pieces mixed with 2 kg of the mixture.
Be sure to pay attention to the removal of miscellaneous potatoes, diseased potatoes and slender buds when cutting, to prevent dead seedlings from growing in the ground or to get sick, affecting potato yield and potato price. 
How to apply potato base fertilizer
Potato seed potato cutting is an important part of high potato yield and potato pest control. Like potato soft rot, potato black rot disease may be transmitted from the cutting process. The following Green Rich Cooperatives will introduce the potato science cutting in detail:
