Application on greenhouse vegetables can not only promote photosynthesis, enhance plant resistance, but also improve the adaptability of seedlings to low temperature, high humidity, low light and other undesirable environments, thereby promoting high quality, early maturing, increasing yield, and increasing income of vegetables. Application of rare earth to tomato can increase the height of plants, speed up the leaves, increase the number of leaves, flowering time 3 to 5 days in advance, the number of fruits per plant increased by 2 to 20, the fruit sugar content increased by 10 to 20%, early maturity 5 to 7 days . Application method: mainly adopt foliar spraying, use 45-50 grams of rare earth per acre, make a solution with 0.1% concentration of water, and spray once during the initial flowering period and the fruit expansion period. Cucumber application of rare earth, can generally increase the previous production by more than 40%, the total output increased by 20%. There are two main methods of application, one is seed dressing.

The application of rare earth in pepper can increase the content of vitamin C in fruits by 13.8% and increase production by 13.7%. Application method: mainly adopt foliar spraying, spraying twice at the whole growth period. The first time before transplanting 10 days or after transplanting to survive, the spraying concentration is 0.03-0.05%; the second time is at the beginning. At flowering, the spraying concentration was 0.08%.
