Prevention of Soybean Yellow Leaf Disease

In recent years, yellow leaf disease has become more common in soybeans and other legume crops. If it is not controlled in time, it will cause serious damage to crop growth. Such as early onset, yellow leaves, short plants, no scab. In the mid-term onset, even if there is scarring, there is no grain, and even if there is grain, it may cause severe loss of production or loss of grain.

The reasons are as follows: First, the long-term use of chemical fertilizers, farmyard manure reduction, resulting in soil compaction. Second, in recent years, the use of combine harvesters and burning of wheat bran has become common and has destroyed the surface structure of the soil. Third, the lack of symptoms is serious: such as iron, calcium and so on. Fourth, bacterial infection is the main cause of yellow leaf disease.

The types of yellow leaf disease can be summarized as: lack of type, bacterial type, lack of sugar type, etc., long-term continuous rain, poor photosynthesis cause plants lack of sugar; appear yellow leaves, so that premature aging, defoliation, falling, resulting in reduced production.

Prevention and control measures: 1. Apply more farmyard manure and improve soil structure; 2. Balance formula fertilization and supplement of trace elements (zinc, iron, sulfur, calcium); 3. Discard wheat bran and protect soil structure; 4. Occurrence of yellow leaf disease It can spray micro fertilizer, spraying zinc sulfate 2 per acre with a fungicide "guarantee" a bag; plant regulator "Green Wind 95" or "Sanri Ling", "Hui Manfeng" (optional one ), eating brown sugar 2 two, three days after spraying green, return to normal.

The open cultivation in our city can safely winterize.  Carrot seeds can germinate at 4~6°C,  but the most suitable germination temperature is 20~25°C;  optimum temperature for growth:  18~23°C during the day,   15~18°C during the night, growth retardation above 25°C,  stagnation under 3°C Grow. Moisture:  Carrot roots are well developed,  the leaves are 3 to 4 pinnate, leaf area is small, water loss is less, so it is more drought-tolerant.We also supplied Fresh Ginger ,Air Dried Ginger , Fresh Garlic , White Garlic ,red garlic.
