Rare earth refers to the general name of 17 metal elements in the periodic table, including lanthanum, praseodymium, neodymium, cerium, samarium and so on. Among them, cerium accounts for 48%, lanthanum 25%, neodymium 16%, praseodymium 5%, samarium 2%, and other 12 elements 4%. In recent years, rare earth has become an important resource for national economy and national defense construction. Not only can it be widely used as an industrial vitamin in metallurgy, machinery, petroleum, chemical industry, light industry, electronics and other industries, but also can be used as micro-fertilizer in agricultural production. In fishery production, feeding rare earths to fish also has a very good effect. According to the test

10 measures to increase soybean production
1. Interseedling: on the basis of the whole seedling, soybean seedlings are carried out when two opposite leaves are unfolded, and the yield is generally increased by 10-20%. 2. Pressing seedlings: when the first compound leaf of some soybean seedlings is unfolded, choose a sunny day at noon and use animal power or machine to induce wood to press along the ridge, which can increase the yield by 8.5-10%. 3. Heart picking: in the early flowering or full flowering stage of soybean, about 2 cm of the top of the main stem is removed by hand, which can increase the yield by 7.2% and 10.8%. 4. application of rare earth: 2 kg of rare earth for every 1 kg of soybean seed, or concentrated at seedling stage and early flowering stage of soybean

Ten ways to increase the yield of Pleurotus ostreatus
The main results are as follows: 1. During the formation and development of Pleurotus ostreatus fruiting body, the temperature difference stimulation of 7 to 12 ℃ per day can promote the early emergence of mushroom and the orderly development of fruiting body. The specific methods are as follows: covering the film for heat preservation during the day, opening the film in the sunny evening or in the morning, ventilating and cooling to increase the temperature difference, and combined with high humidity management to induce mushroom production. 2. the high humidity stimulation method first opens the bacterial bed (or clove) to dry for 1 / 2 days, and then sprays water 2 / 3 times a day for 2 / 3 days to slowly absorb water and culture medium on the surface of the fungus.
