Techniques of planting and raising seedlings of pomegranate in summer

1. During the cutting period, pomegranate seedlings were propagated by using lignified or semi-lignified green branches in summer, mostly from June to July. two。 The green branches are generally selected in the early morning or on a windless cloudy day. From the excellent mother plants with many fruits, good quality and strong tree strength, the sturdy green branches that are disease-free and newly lignified in the current year should be cut with a thickness of 0.8 cm to 1.5 cm. 3. Soak the cutting medicine in a cool place and cut the branches into cuttings of 15cm to 20cm. In order to prevent the evaporation of water, two leaves are kept at the top. Tie every hundred cuttings together and immediately place the lower end of the cuttings in 500mg / L NAA solution or soak in 5% sucrose solution for 3 minutes. 4. Timely cutting the cuttings soaked with chemicals and cutting them into a 120 cm wide seedbed with river sand as the substrate. According to the row spacing of 10 cm × 30 cm, the cuttings were obliquely inserted into the soil, and the upper end of the cuttings was exposed. 5. Sprinkle water for shading and then sprinkle water and shade 50-80 cm above the seedbed. From then on, water is sprayed every morning and evening to maintain soil moisture. After the cuttings take root and begin to grow new leaves, then gradually withdraw from the shade shed. 6. When the seedling height was 2 cm, urea was applied to 5-7.5 kg per mu of seedling bed. Wipe out too many buds in time, leaving 1 or 2 new shoots. Loosen the soil and weed, accelerate the growth of seedlings. In September, control nitrogen fertilizer, increase phosphorus and potassium fertilizer, promote seedling branch tissue maturity and prevent overgrowth.
