Edible Mushroom Fertilization Techniques and Key Points for Spring Flower Management

In early spring, temperatures turn warmer, rainfall is abundant, and relative humidity is relatively high. At this time, flowers and trees are in the transition from dormancy to budding and growth, making it the best season for transplanting all kinds of flowers and trees. For flowers and trees planted in large patches where some plants are missing, it is also a great opportunity for replanting. Therefore, time should be seized to carry out transplanting and replanting, and the opportunity must not be missed.

II. Reasonable Fertilization

"A plant's bloom depends entirely on fertilizer." Whether fertilizer is sufficient or not is an important factor determining whether flowers and trees grow well, especially for flowers and trees planted in poor soil, where fertilization is even more important. When fertilizing, prevent concentrated fertilizer from damaging the roots. Chemical fertilizers must be applied diluted, and human waste, cake fertilizer, etc. must be fully fermented and decomposed before application. At the same time, pay attention to the ratio of nitrogen, phosphorus, and potassium, and do not apply only nitrogen fertilizer.

III. Pruning and Shaping

Spring is the season when all kinds of flowers and trees sprout and grow leaves, and it is also a good time for shaping. Spring is the most suitable season for heavy pruning. At this time, all kinds of flowers and trees have abundant stored nutrients in their bodies. After heavy pruning, not only will growth not be affected, but through pruning, growth points are reduced and nutrients are concentrated, so that the remaining buds sprout uniformly and the plants grow robustly.

IV. Pest and Disease Control

As temperatures rise and the tender buds of flowers and trees grow, various pests and diseases of flowers and trees follow. As a manager, one should inspect flowers and trees at any time and apply targeted control. At present, the main chemical pesticides used for pest and disease control include: 40% omethoate at 1000 times dilution for aphids, pyrethroids (such as 2.5% deltamethrin, 20% fenvalerate) at 2000 times dilution for butterflies and moths of the order Lepidoptera, 20% dicofol at 800 times dilution for mites, and 40% omethoate at 1000 times dilution for scale insects, but the control timing must be grasped at the peak hatching period of the first-generation nymphs, with mid-May to early June being the critical period. Once the nymphs have formed a protective waxy shell, general pesticide control becomes very difficult. For disease control, prevention is more important than treatment. For those flower and tree varieties prone to disease, frequent inspections should be carried out. Once a small number of disease spots appear, spraying should be done promptly for control. However, some diseases have pathogens that invade as early as the bud stage. For these diseases, pesticide spraying should be carried out early for control. Generally, 70% thiophanate-methyl at 700 times dilution or 50% carbendazim at 500 times dilution can be used, spraying once every 7 days for 2 to 3 consecutive times for comprehensive control.

V. Drainage and Flood Prevention

Spring has abundant rainfall, and generally waterlogging damage is greater than drought damage. In southern regions, prevent water accumulation from causing root rot and death of flowers and trees. For flowers and trees planted in large patches, drainage ditches should be well opened to promote root growth. (Source: Agricultural Expo Network)
