The spring is a critical period for citrus to restore its vigour and flowering results. Therefore, it must be taken seriously to lay the foundation for the steady production of citrus.
Apply early to spend fruit fertilizer. It is advisable to use a mixture of chemical fertilizers, cake fertilizers and farmyard fertilizers in order to dig deep ravines. It is usually conducted from mid-February to mid-March. The amount of fertilizer should account for about 40% of the year. If it is a big year tree, it should be fertilized more.
Spring trim. The pests, stems, dry branches, aging branches and some winter shoots were completely cut off, and the wounds were cut off in time to prevent the anti-corrosion film from closing in time to ensure good differentiation of normal flower buds.
Prevent pests and diseases. Early spring due to temperature rise, to prevent the spread of bacteria can be used 600 to 800 times the prevention of new high-fat membrane.
Protect the trunk. By coating the trunk with a whitening agent, a large number of adult and insect Eggs and pathogens that are parasitic on the trunk can be killed. The proportion of whitening agent is: 5 kg of lime, 0.5 kg of sulfur powder, 150 g of salt, and 15 to 20 kg of water. Add 50 grams of tung oil per 50 kilograms of whitening agent, no tung oil plus oil. Lime sulfur slag can also be used as a whitening agent.
Garden cultivators. Cultivating is conducive to multiple root absorption and increased nutrient absorption surface. The cultivator can also significantly reduce the population of insect populations, and can also ripen the soil and improve soil texture.
Timely irrigation. In general, drought often occurs in spring, which is unfavorable for flower bud differentiation and fruit setting. If timely irrigation, can significantly increase production by more than 15%.
Clean the garden. Many fruit growers believe that the work of the Qingyuan Garden will only be carried out in the winter. In fact, this work is a perennial important work. Should the park litter, decaying fruit, weeds, and crop culverts and pruning of the branches and other diseases, insects, bacteria and mycoplasma, were transported out of the park burning or buried deep processing.
