Trace element water soluble fertilizer specific what effect?

When the trace elements required by crops are sufficient, the growth will be very vigorous. If there is a lack of species or several elements, the growth of plants will be affected and various problems will occur. Trace elements play a vital role in the growth and development of plants. What are the specific effects of trace element water-soluble fertilizer? Can it be used for crop cold and antifreeze?

1. trace elements water soluble fertilizer efficacy:

1. The copper element contained in this product can lock the loss of trace elements in crops and improve the disease resistance of crops.

2. Promote the transfer and transportation of photosynthesis products to fruits, promote flower bud differentiation, improve fruit setting rate, and promote fruit coloring.

3. Directional input of nutrients, rapid transformation of vegetative growth to reproductive growth, promote large fruit, uniform fruit, beautiful fruit, good fruit taste, anti-cracking fruit.

4. Alleviate soil compactization, and can catalyze the absorption and utilization of soil nutrients.

2. for greenhouse vegetables cold protection

1, strengthen field management, foliar spray nutrients cold resistance

In winter, the temperature is low and the light is weak, and the absorption ability of the root system is weak. It is recommended to spray trace element water soluble fertilizer on the leaf surface to supplement the deficiency of the root system caused by insufficient absorption of nutrients. Foliar spray rice vinegar can inhibit bacteria and insect repellent, mixed with sugar and calcium superphosphate, can increase the sugar content and hardness of mesophyll, improve cold resistance. Use less or no growth hormones to prevent reduced cold resistance.

2, early prevention, reduce the occurrence of diseases

Low temperature is unfavorable to facility vegetable production, especially the humidity in the shed is increased due to the reduction of ventilation time, which creates conditions for the occurrence and prevalence of diseases.

Disease prevention and control should follow the principle of prevention in advance. When bad weather such as rain, snow, haze and haze comes, protective fungicides such as chlorothalonil and carbendazim can be sprayed for prevention. If the use of traditional spray control, should minimize the number of control to reduce the humidity in the shed, in addition to spray can be combined with amino acid foliar fertilizer mixed use.

3, timely replenishment, heat preservation to prevent freezing injury

The specific heat of water is higher than that of air, the heat dissipation is slow, the indoor soil moisture content is moderate in winter, the pores and cracks of the plough layer are fine, the root system is not suspended, the soil is insulated, and the root system is not subject to freezing damage. Therefore, the freezing injury of seedlings is mostly caused by water shortage. For this reason, sufficient water can be poured before winter or good weather (watering above 20 ℃) can be selected to prevent freezing injury.

4, scientific ventilation, supplement carbon dioxide

The ratio of carbon and nitrogen to the yield of vegetables is 1 ∶ 1, and the requirement of vegetables to the ratio of carbon and nitrogen is 30 ∶ 1. At present, the majority of growers have realized the effect of nitrogen, but ignored the effect of carbon.

Greenhouse vegetables are easy to grow yellow in winter. One hour after the sun comes out, carbon dioxide produced by vegetable respiration and soil microbial decomposition at night can be absorbed, and carbon starvation will be in place around 12 noon. When the temperature is high, the greenhouse film can be opened and closed, put into the outside carbon dioxide, improve vegetable resistance and yield. When the temperature is low, the shed is closed and carbon dioxide is artificially added, which can enhance the cold resistance of vegetables and increase the yield.
