Spring Pruning Methods and Technical Key Points for Densely Planted Jujube Trees
The small canopy open-center layered form has a trunk height of 80-90 cm. Suppress the secondary branches on the trunk and promote the development of 3-4 jujube heads (main shoots), so that the topmost jujube head extends upward to become the trunk extension branch, and the 2-3 jujube heads below are trained as main branches. In the second year, cut back the trunk branch leaving about 60 cm, and remove the

Spring Fruit Tree Watering Time: When Is It More Scientific to Water
Abstract: After the beginning of spring, water the fruit trees before bud break in combination with fertilization, then water during the rapid shoot growth period, which is the critical period for water demand. In actual production, whether fruit trees need watering is generally determined by soil moisture conditions and drought conditions. During this period, the suitable soil water-holding capacity of the orchard is 60%-80%. When watering, the water should infiltrate 30-50 cm into the soil. Do not flood irrigate, to prevent excessive new shoot growth and adverse effects on flower bud differentiation.
