Vegetable fields are difficult to grow, fertilization is inefficient,

Due to sufficient sunlight and suitable climate, South China has been one of the main producing areas of vegetables in my country for a long time.

But in recent years, with the frequent occurrence of vegetable diseases, pests and weeds, vegetable farmers have found that vegetable diseases, pests and weeds have become more and more difficult to treat, and it is also more and more difficult to grow vegetables. With increasing attention to safety, large-scale vegetable planting has gradually become the mainstream. Consumers' demands for vegetables are not only good-looking, but also delicious and safe.

The vegetable industry in South China has reached the brink of change.

On May 24th, the South China Vegetable Disease and Pest Resistance Management Summit Forum hosted by the Southern Newspaper Media Group Nanfang Rural News Agency came to a successful conclusion in Huizhou.

The conference attracted many vegetable growers from South China, and also 5 agricultural companies that have served in the South China vegetable area for a long time. In response to the many current problems faced by vegetable planting in South China, they combined their years of service experience to give feedback. Made quite practical suggestions.

Zhi Huyu, deputy director of the "Innovative Theme" division of Guangdong Plant Dragon, pointed out that the current soil problems in my country are severe, especially in the vegetable growing areas in the south, where soil salinization, compaction, and heavy metal residues are serious. Upgrade is imminent.

How to improve? Zhi Huyu recommends "Shangcanli" silkworm excrement bio-fertilizer. It is understood that "Shangcanli" is a bio-organic fertilizer launched by Plant Dragon based on the pesticide-free and antibiotic-free silkworm excrement, which has the ecological effect of improving soil. , It has a significant effect on improving fertilizer utilization and improving beneficial bacteria in the soil.

Li Zhongqi, agrochemical specialist of the Product Market Development Department of Sumitomo Fertilizer (China) Enterprise Group, suggested that "Vegetables grown in the soil, although the soil can supply some nutrients, are always limited. Scientific fertilization is based on the soil nutrient supply capacity and vegetable demand. Determine the formula, do not apply too much, and do not apply too much to avoid waste, environmental pollution and negative effects on the vegetables themselves." Therefore, the selection of fertilizer is different in different periods of crop growth.

Li Zhongqi suggested using long-lasting fertilizer for base fertilizer, such as Sumitomo's urea-formaldehyde compound fertilizer, which can be combined with organic fertilizer. In the vegetable growth period, high-nitrogen fertilizer is the mainstay; in the reproductive growth period, the input of phosphorus and potassium fertilizer should be increased; in the quality formation period, the application of nitrogen should be appropriately reduced, and the input of potassium should be emphasized. According to the actual situation, proper amount of micro-fertilizer should also be applied to ensure nutritional balance.

In response to the pest resistance problem that many vegetable farmers are concerned about, Yao Zhenwei, a field scientist at Dow AgroSciences in the United States, said, "Some vegetable farmers find that a medicine is easier to use, and they will use it until the medicine is used to death, so a single medicine should be contraindicated.

He pointed out that the mixed use of Dow AgroScience's "Irish" and "Tefal" in different proportions can effectively solve the problem of resistance to pests caused by a single drug, and it is extremely strong against vegetable pests such as jumping beetles and thrips. The killing effect.

At present, my country’s serious environmental pollution problems, especially the improper use of agrochemical products, have brought great pressure to environmental governance. Coupled with the recent frequent occurrence of food safety problems, Deng Weiming, the sales director of Foshan Daxing Biochemical Co., Ltd. believes that "production is efficient, Safe agrochemical products are extremely important."

For this reason, Daxing has developed a series of safe and efficient products in response to this situation. For example, "Easy Kill" has an effective rate of over 90% for the prevention and control of Plutella xylostella, and "Battle Armor" as a jumper's nemesis is effective and has a high mortality rate. specialty.

Liu Guanbin, marketing director of Huizhou Yinnong Technology Co., Ltd. pointed out that “pesticides are sometimes terrible, but sometimes they are very safe. The key is to see how you choose and use them.” It is very important to select a product produced by a regular manufacturer. To judge whether a product is produced by a regular manufacturer, first look at whether the manufacturer and certificate number are marked on the label. A regular product will clearly indicate the ingredients and content of the product, the dosage form and toxicity of the product, etc. .

Regarding the thrips, which have been rampant on beans recently, Liu Guanbin said, “It’s not that thrips are too stubborn, but that we have chosen the wrong medicine and method of use.” He gave an example. The "Nongzhou Xing" launched by Yinnong has always been positioned as a special medicine for fighting armyworms. It has a strong ability to kill beet armyworms and others. The low-dose "Nongzhou Xing" hardly has any effect on thrips." Adjusting its content to 50g/30 kg of water can kill thrips and bean pod borers as high as 90% and has no toxic side effects on vegetables." Liu Guanbin said.
