1. The application of rare earth in tomato can increase the number of fruit per plant in tomato by 5-10. Application method: 45-50 grams of rare earth per acre, and a solution with a concentration of 0.1% in water, sprayed once in the initial flowering stage and the young fruit expansion period.
Second, cucumber can increase the yield of cucumber by 20%. Application method: 1 seed dressing. First, 1-2 g of rare earth is dissolved in 1.5 kg of water, and then sprayed on the cucumber seeds, while spraying and mixing, drying and sowing. 2 foliar spray. 10 grams of rare earth per acre, the solution of water to a concentration of 0.03%, first spray in the middle of the first flower, and then spray again about 20 days.
Third, pepper can increase the yield of pepper by 13.7%. Application method: spray twice in the whole growth period, the first time 10 days before transplanting, the spraying concentration is 0.03%-0.05%; the second time in the initial flowering period, the spraying concentration is 0.08% .

The AIN crystal is a covalently bonded compound with a [AIN4] tetrahedron as a structural unit, and has a wurtzite structure and is a hexagonal system. Chemical composition AI 65.81%, N 34.19%, specific gravity 3.261g / cm3, white or grayish white, single crystal colorless and transparent, sublimation decomposition temperature under normal pressure is 2450 °C. It is a high temperature heat resistant material. Thermal expansion coefficient (4.0-6.0) × 10 -6 / ° C. Polycrystalline AIN has a thermal conductivity of 260W/(MK), which is 5-8 times higher than alumina, so it has good thermal shock resistance and can withstand extreme heat of 2200 °C. In addition, aluminum nitride is not attacked by aluminum liquid and other molten metals and gallium arsenide, and particularly has excellent corrosion resistance to molten aluminum liquid.
