The amount of fertilization of peach trees should be determined flexibly according to soil fertility, tree age, variety, yield, and climatic factors. In orchards with low soil fertility, high age and high yield, the amount of fertilization should be higher; the fertilization amount of orchard with higher soil fertility, small age and low yield is appropriately reduced. For medium-yield orchards, it is recommended to apply 1000-2000 kg of decomposed organic fertilizer per mu, and Stanley 45% potassium sulphate compound fertilizer 80-100 kg. The high-yield garden can increase the amount of fertilization.
Applying base fertilizer
Peach tree roots can absorb nutrients and produce new roots at lower temperatures. Spring growth activities begin early, and early new shoots grow vigorously. In the autumn, the roots of the peach trees can heal and produce new roots in a short period of time, and the autumn base fertilizers bloom earlier than the spring application base fertilizers, the total number of flowers increases, the flowers are large, and the fruit set rate is high. In addition to organic fertilizer, the base fertilizer should be applied with Stanley compound fertilizer, and the dosage should account for about 60% of the annual fertilization amount. The autumn base fertilizer is combined with autumn tillage before the leaves, and can be applied by radiation ditch or annular ditch, and the depth is about 30-45 cm, so that the main root distribution layer is suitable.
Reasonable topdressing
Top dressing before flowering: It is applied before flowering in early spring, which can promote germination, promote the healthy growth of new shoots, and reduce the falling flowers and fruits. The applied fertilizer should be based on high-nitrogen compound fertilizer, and the dosage should account for 5% to 10% of the annual fertilization amount. If the amount of base fertilizer is higher or the base fertilizer is applied in winter, it may not be topdressed before flowering.
Post-flowering top dressing: more than after flowering and before fruit nuclear hardening, post-harvest topdressing can increase fruit setting rate, improve tree nutrition, and promote rapid growth of fruit in the early stage. The amount of fertilizer applied is about 5% to 10% of the annual application rate.
In the expansion period, the top dressing is applied after the fruit enters the rapid growth period again. At this time, the top dressing plays an important role in promoting the rapid growth of the fruit, promoting the flower bud differentiation and improving the storage nutriage of the tree. In this period, the topdressing fertilizer is mainly high-potassium compound fertilizer, and the dosage is about 20% to 30% of the annual application amount.
Solenoid water valve is a type of Solenoid Valve that is controlled by an electromagnetic solenoid. They are used to control the flow of water in a variety of applications, including coffee machine, water dispenser, baby milk machine etc. Solenoid water valves are typically made of brass or stainless steel and are available in a range of sizes and configurations to suit different applications. They can be 2-way normally clsoed water valve or 3-way solenoid water valve. Solenoid water valves are reliable and efficient, making them a popular choice for many different industries.
