Fertilization techniques and methods of Edible Fungi and key points of Flower Management in Spring

In early spring, the temperature becomes warmer, the rainfall is abundant, and the relative temperature is higher, when flowers and trees are in the transition from dormancy to budding and growth, which is a good season for all kinds of flowers and trees to transplant. It is also a good time to replant those flowers and trees that are planted in pieces and lack of plants. Therefore, we should seize the time to transplant and replant, and do not miss the opportunity.

II. Rational fertilization

"if a plant has a flower, it all depends on fat." Whether the fertilizer is sufficient or not is an important factor to determine the growth of flowers and trees, especially for flowers and trees planted in poor soil. When fertilizing, it is necessary to prevent thick fertilizer from harming the roots. Chemical fertilizer must be applied lightly, and human feces, urine and cake fertilizer must be fully fermented and ripened before they can be applied. At the same time, we should pay attention to the ratio of nitrogen, phosphorus and potassium, not simply applying nitrogen fertilizer.

Third, trim styling

Spring is not only a season for all kinds of flowers and trees to sprout and grow leaves, but also a good time for modeling. Spring is the most suitable season for heavy pruning, when all kinds of flowers and trees are rich in nutrients. After re-pruning, not only will not affect the growth, but through pruning, reduce the growth point, concentrate nutrients, so that the remaining bud sprouting neatly, the plant growth is strong.

IV. Pest control

With the rise of temperature and the growth of flowers and trees, all kinds of diseases and insect pests follow. As a manager, flowers and trees should be inspected at any time for symptomatic prevention and treatment. At present, the main chemical pesticides used for pest control are as follows: 1000 times of omethoate for aphids, 2000 times of pyrethroids (such as 2.5% of dimethoate, 20% of quick kill) for Lepidoptera insects, 20% of dicofol for mites, 1000 times of omethoate for scale insects, but the control time must always be in the peak incubation period of the first generation of larvae. The period from mid-May to early June is a critical period. When the young scale forms a protective wax shell, the general pesticide control is very difficult. Prevention and control of diseases is more important than treatment. For those varieties of flowers and trees that are prone to disease, they should be checked frequently. Once a small number of disease spots appear, it is necessary to pay close attention to spraying prevention and control, but there are also some diseases, and germs have invaded as early as the bud. For these diseases, spray control should be carried out as soon as possible. Generally, 70% thiophanate methyl 700-fold solution or 50% carbendazim 500-fold solution can be sprayed every 7 days for 2 to 3 consecutive times for comprehensive control.

V. drainage and waterlogging prevention

Rain Water is rich in spring, generally waterlogging damage is more than drought damage, in the southern region to prevent stagnant water caused by flowers and trees root mildew and death. Flowers and trees planted in patches should be well drained to promote root growth. (source: agricultural Expo Network)
