Seeds of fruit trees planted in spring are generally treated with stratification to produce seedlings. If there is no time to piling up in the winter, is there any way to deal with it in spring? The following describes the specific treatment of new methods. In the middle and late March, put the seeds of the peach into a large iron pot filled with cold water, stir it thoroughly with a wooden stick, and then remove the bad seeds, such as dull, moldy, and rotten, floating on the water. Then put the good seeds into the tank and immediately pour five cold water into the tank and stir it with a wooden stick. After 10 minutes, remove the fish and put it in another jar, then pour it into cold water. The amount of cold water poured in is based on the complete soaking of the seeds. The soaking time is 7-8 days. Cold water must be changed once a day so that the seeds can absorb enough water in a short time. Seeds are soaked for 7-8 days and then mixed with 5 parts of wet sand and 2 seeds. The seeds are placed on the back yin and piled on the heap. A 6-7 cm thick wet sand is placed on the pile and the straw is covered with wet sand. Straw should be sprayed at any time to maintain the sand moisture. The stacked seeds should be turned up and down every 10 days or so. Stacking time is about 1 month. When the seed is turned during the accumulation, if it is found that the humidity is too low or the temperature is too high, it is necessary to spray cold water at any time to maintain the appropriate humidity or reduce the temperature. Humidity in the process of accumulation should not be too large, so as not to cause mildew. Around mid-March and mid-April, the piled seeds were moved to the sun, spread to a depth of 50 cm and covered with straw to prevent birds from feeding. Turn once every 2-3 days to prevent the seed from becoming rotten. When the seeds are germinated by more than 50%-60%, sowing can be carried out.
