The citron is a deciduous tree of the deciduous family. The trunk is straight, and young shoots and young leaves can be eaten as vegetables. If you miss the opportunity to raise seedlings in the spring or if you fail to grow seedlings, you can also do summer nursery. First, soil preparation before planting 5000 kg of compost per acre, nitrogen, phosphorus, potassium compound fertilizer 100 kg, more than 30 cm deep tillage, require uniform fertilization, soil broken, leveling. After the site preparation, a 0.5-meter-wide sorghum is made. Drought can be watered and rain and water can be drained. Second, sowing new seeds collected in the previous year, the germination rate can be more than 40%. Soak it in cold water for 12 hours before sowing and remove it for sowing. Use a raft to open the ditch, each trip 2 lines, spacing 20 cm, cover soil 0.5 cm, 4 kg per mu. Third, after the broadcast management due to high temperatures in summer, more rain, is not conducive to the germination of camphor, can take the shady shed or shading net shading, grass can also be controlled to the ground temperature below 25 °C, spray with a sprayer, the soil moisture control From 16% to 18%, budding occurs after about 13 days. 800 times after sprouting spray epichlorohydrin disease prevention. When the seedlings are 10 cm high, they are combined with cultivators and weeds to perform the seedlings with a spacing of 10 cm. To cultivate good quality seedlings, spray 0.02% urea or potassium dihydrogen phosphate once every 7 days, spray 4 times, and spray 25% triadimefon 2000 times to prevent rust.
