How to manage prickly ash trees in spring? Latest technical method tutorial
The prickly ash tree is an important economic tree species and is now a wealth-building project in many regions. It is planted in many areas, and to ensure high yield and high quality of prickly ash trees, special care must be taken in management every spring. Now let's take a look at the spring management techniques for prickly ash trees together.
1. Fertilizing and spraying fertilizer
During the growth and development of prickly ash trees, a large amount of nutrients needs to be absorbed from the soil, so in addition to applying base fertilizer immediately after picking, topdressing should be done 2 times in spring and summer. The first time is in April-May, applying human and livestock manure, paired with a small amount of nitrogen fertilizer. The second fertilization is in June-July, applying a quick-acting chlorine fertilizer once, mixed with a small amount of phosphorus and potassium fertilizer, to promote high yield. Fertilization can adopt the methods of hole application and ring-shaped trench application. Dig holes at the drip line of the tree canopy, and cover with soil immediately after fertilizing to prevent the fertilizer efficiency from volatilizing. In addition, after the flowers fade, immediately spray potassium dihydrogen phosphate foliar fertilizer 2-3 times, which can produce excellent results.
2. Shaping and pruning
Old and weak trees are suitable for pruning in spring, while vigorously growing young trees can be pruned in summer. Spring pruning mainly adopts methods such as pulling, pressing, propping, and bracing to open the angle of the main branches. Old trees should be rejuvenated and restored, making full use of water sprouts. Weak trees should be pruned relatively heavily to stimulate their growth. Summer pruning mainly involves pinching and heading back water sprouts to reduce nutrient consumption as much as possible. Dense branches should be removed in time to allow ventilation and light penetration.
3. Intertillage and weeding
The soil mounds built up in winter to prevent freezing should be opened up promptly after temperatures rise in spring. At the same time, the tree basin should be re-dug to increase the water content of the soil under the canopy. The size of the tree basin should be close to that of the canopy. In the rainy season, the soil mound at the root collar should be piled higher to prevent excessive water accumulation. Prickly ash trees are afraid of weed overgrowth, so after the beginning of spring, intertillage and weeding should be carried out once generally. At the same time, several more weedings should be done throughout the year's growth process to prevent weed overgrowth. After the weeds are sun-dried, they should be buried in trenches to increase soil fertility.
4. Pest and disease control
Pests and diseases are a major obstacle in prickly ash production, directly affecting the yield and quality of prickly ash, so pest and disease monitoring and control work should be done well starting from spring, to reduce the harm caused by pests and diseases as much as possible.
