Field Management Techniques for Pollution-Free Mango Cultivation
(1) Soil management: In combination with the application of base fertilizer, dig a trench on each side of the tree canopy below the drip line. The standard trench size is 100 cm x 50 cm x 40 cm, and green manure, decomposed organic fertilizer and phosphate fertilizer are pressed into it. It is recommended to interplant dwarf leguminous green manure, forage grass, other nectar source plants or grow grass between the rows of the mango orchard, but the intercrops should be at least 1 m from the base of the mango trees. The grass species selected should be short-stemmed or creeping, share no common pests or diseases with mango, and have a short growth period, such as Ageratum conyzoides (goatweed). It is recommended that the root zone or planting strip of mango be covered year-round.

Key points of pollution-free control techniques for citrus cultivation
When chemical pesticides are used to control citrus pests and diseases, costs are high and resistance is easily developed. Guiding fruit growers to use the following simple and economical methods gives good results in controlling certain citrus pests and diseases. The specific control methods are as follows. 1. Plant ash to control citrus leafminer: during the shoot-flushing period, start when the new shoot has grown to about 3 cm, and continue until the new shoot matures, sprinkling once every 5-7 days for 5-6 consecutive times, and during the interval, replenish promptly after rain. In the early morning when the dew has not dried, or after rain, or after watering, promptly sprinkle plant ash onto the upper and lower surfaces of the leaves of the new citrus shoots. Throughout the shoot period, the leaves should remain constantly coated with the ash powder until the shoot leaves mature. This method is suitable for greenhouse or open-air citrus nurseries, young citrus orchards, and potted ornamental citrus for controlling citrus leafminer.

What are the care methods for citrus trees after freezing damage
After a citrus tree is damaged by freezing, the aboveground part suffers varying degrees of injury or dieback, while the underground part is generally less damaged. Post-freeze care measures mainly make use of its relatively intact root system to promote the sprouting of new branches, restore the canopy as quickly as possible, and gradually achieve the goal of normal growth and fruiting.
