A certain number of grassy handles are buried in the concentrated distribution area where the fruit trees absorb roots, and mulching is performed to temporarily store the applied fertilizer and water, reduce the loss, and gradually release nutrients and water, so that the fruit trees can be supplied with stable water supply throughout the year. Improve the growth and development of fruit trees to achieve the purpose of increasing production and strengthening trees.
Its advantages are to improve the ground temperature in early spring, save water-saving fertilizer, improve the survival rate of saplings, and increase the production of strong trees. The cost is low and the benefits are significant. This technique can be used on apples, pears, apricots, plums, etc., and is usually carried out before or after flowering each year in early spring.
Large trees can be set up four to eight points, two saplings, caves generally 25 to 30 cm in diameter, the depth of the hole 35 to 45 cm, will be bundled with straw (used as straw or weeds can be uniform, the grass to bundle the diameter 15 to 25 centimeters long, 30 to 35 centimeters long, soaked in water before burying) Vertically bundled into the hole, apply superphosphate at the bottom of the hole, 50 to 100 grams per hole, back to fill the soil to be practical, the grass cover the top to the soil When 1 centimeter, apply 50-100 grams of urea, such as the application of ammonium bicarbonate, to be applied when the backfill soil is 20 centimeters from the ground, and then fill the soil, then water, then cover l cm thick soil, buried in the hole After the ground is lower than the ground 1 to 2 cm into a small amount of water in order to accumulate water, then in the film covered above the center of the hole and put a small hole in the film, pressing a small stone, in order to facilitate the accumulation of rain and water.
In the dry season, water is poured every 10 to 12 days. Each time, each hole is poured 3.5 to 5 kg. Generally, after anthesis, the new shoot is long-term, and after harvesting fruit, it is combined with rainfall or pouring and irrigation to apply topdressing, applying 50 to 100 grams of compound fertilizer or urea each time.
