At present, sprouts are mostly supplied to hotels and restaurants, which spread rapidly from big cities to small and medium-sized cities. When hotels and restaurants list pea seedlings and sprouts on the menu, they are required to supply them continuously! Therefore, sprouts must be cultivated and supplied all the year round. In order to do a good job in annual production and balanced supply, the following points should be paid attention to in production: ① Pay attention to the continuous supply of seeds. We must find a stable and completely reliable source; There should be more room for seed storage, especially to ensure the use of seeds when the green and yellow are not connected. Under conventional storage conditions, the seeds of Toona sinensis will lose their germination rate quickly after experiencing high temperature in hot summer, so special storage methods must be adopted to ensure the continuous use of the seeds. The specific methods are as follows: one month before the arrival of high temperature season (before the end of May in North China), dry and complete Toona sinensis seeds with germination rate higher than 90% (without removing wings) are put into plastic bags made of double-layer agricultural films, each bag has a capacity of 5- 10 kg, then sealed and welded, covered with woven bags, and then placed in a refrigerator at 0-4℃ (if the storage capacity is large) (2 If the temperature can't reach the suitable temperature range, it will bring a lot of trouble to the cultivation management. ③ Pay attention to different kinds of collocation. Because of the different requirements for temperature conditions of various sprouts, when arranging production in winter or summer, the output of various sprouts can be appropriately adjusted to expand varieties that can better adapt to the cultivation environment at that time and compress varieties that are not suitable. For example, in cold winter, it is advisable to produce more varieties with strong cold tolerance, such as pea seedlings, seed buds, alfalfa buds, etc. In hot summer, radish seedlings, buckwheat seedlings, water spinach seedlings and other more heat-resistant varieties can be produced.
