【1】 Lawn fertilization technology

1. In February (south of Guangzhou), decomposed organic fertilizer can be applied in March, April, and November (south of Beijing), and instant compound fertilizer can be applied once a month during the growing season from May to October, and every year before overwintering One additional application of organic fertilizer to the lawn can improve the ability of the lawn to survive the winter safely. From December to January, fertilization is prohibited.

2. The daily fertilization time should be carried out after 3 pm. Fertilization must be irrigated to avoid fertilizer damage. In addition, lawn fertilization is generally carried out one to two days after mowing, and it should not be fertilized before or just after mowing, so as to avoid waste of fertilizer and damage to the lawn.

3. When fertilizing, spread evenly, generally 20-25 grams per square meter of compound fertilizer. When purchasing fertilizer, you must choose the products of regular manufacturers. When fertilizing, be sure to avoid uneven spreading.

[2] Arbor fertilization technology

1. The roots of trees can be applied with basal fertilizer once from December to February, with organic fertilizer as the main ingredient and a small amount of high-phosphorus-potassium compound fertilizer. Fertilizer is applied every 2 months during the growth period from March to November; Apply fertilizer once before and after flowering.

2. The type of fertilizer to be applied and the amount of fertilizer applied should be differentiated according to the tree species, growth characteristics, planting time, and growth potential of the trees. For the trees in the vigorous growth period, we should pay attention to increasing the application of nitrogen fertilizer; for the flowers and fruit trees, we should increase the application of phosphorus and potassium fertilizer, and even spray boron and zinc fertilizer on the foliage.

3. Fertilization should be combined with watering and soil loosening. After fertilization, the trees should be observed, and if problems are found, they should be irrigated in time to prevent fertilizer damage. When fertilizing, avoid a single fertilization concentration that is too large, and avoid fertilizing too close to the main root.

【3】Shrub fertilization technology

1. Shrubs generally have more lateral roots, more lateral root systems, and shallow root layers. Pay attention to the amount of fertilization and the distance when fertilizing. Also pay attention to whether pruning is often done, and nitrogen fertilizer should be added to shrubs that are often pruned. Shrub fertilization is generally applied 1-2 times of organic fertilizer in early spring and late autumn each year; during the growing season (applying compound fertilizer once a month from April to October).

2. Fertilization of frequently pruned shrubs should be done after pruning. Water should be filled in time after fertilization.

[4] Fertilization of ground cover plants

Long-acting organic fertilizer can be applied 1-2 times in March, April, November, and December; compound fertilizers shall be applied once a month from May to October, and phosphorus and potassium fertilizers shall be applied before the flowers are viewed; Fertilization is prohibited during the slow growth period. If necessary, foliar fertilizer should be sprayed to supplement it.
