Doing a good job in the selection and retention of bitter gourd is an important part of the harvest for the coming year, which involves the cultivation of good melons and the selection of good species. First of all, to isolate the anti-mix. Bitter gourd is a cross-pollinated crop, and other bitter melon varieties can be planted at least 2 km away from the planting field. Otherwise, it is easy to naturally cross the powder between different varieties, so that the seed is not pure. Second, do a good job of artificially assisted pollination. During the flowering period of bitter gourd, it is necessary to carry out artificial supplementary pollination in order to increase the yield of retained seeds.
The bitter melon seed should be kept in combination with the fruit harvesting. After the bitter gourd is harvested 2 or 3 times, it begins to enter the vigorous fruiting period and can be kept. Plants with strong growth, no pests and diseases, and many fruits, and the shape of the cultivar are selected as the retention strains. Choose 2 to 3 fruits close to the base for seeding. The remaining young fruits are removed early to concentrate nutrients for growing melons. When the melon has been fully matured and has not turned yellow, it should be harvested. Cut the Guadi part about 5 to 7 cm with a knife, take out the internal seeds, and the fruit can still be sold. At this time, the melon has turned bright red, which is a symbol of maturity. After the bitter gourd seeds are taken out, the seedlings should be washed away with water, and the bitter gourd seeds are spread out and dried, placed in a sloping bag, and stored in a dry and ventilated place. You can also use the glass bottle to fill the glass, first put 3 to 5 cm thick fresh husk ash in the glass crucible, then put the seeds, and then cover it with chaff ash, then store it in a cool and ventilated place.
Single crystal Calcium Fluoride Lenses or Calcium fluoride windows are ideal for high performance imaging and laser systems.
Calcium Fluoride (CaF2) is an optical grade glass which has an extensive transmission range from UV, visible and IR. Especially, Calcium fluoride has a high transmittance from 200nm to 7μm. The transmittance of uncoated Calcium Fluoride window can up to 94% due to its low absorption and low index of refraction.
We offers high precision and quality caf2 window with cost-benefit price as well as stable supply ability. Dimensions and shape depends on your project, CaF2 drilled window, Caf2 Irregular Window could be customize. Meanwhile, experienced engineer could advise you professional advices according to your applications, drawing is aslo available.
Besides CaF2 window, other Infrared Window such as Zinc Selenide windows, CaF2 window, sapphire window and other High Precision Optical Glass Window are available upon request.
