I. Peanut Blight
The disease mostly occurred from the seedling stage of peanut until the end of its harvest. Spring peanuts were from May to June and summer peanuts were from September to October. The incidence rate was heavier. The susceptible plant initially had a soft sag in the parietal lobe, followed by wilting of the entire plant leaf, but the withered leaves remained greenish blue, and the stem was dissected. It could be seen that the transposed tissue near the ground part had turned brown and was handcuffed. At the point of the cut, the stained white bacteria flowed out, the diseased plant was pulled up, and the roots had rotted and turned dark brown. The prevention measures are as follows:
1. Rational rotation, and the implementation of a reasonable rotation with non-parasitic crops, such as peanuts and corn rotation can eliminate the bacteria in the soil;
2. Select resistant varieties such as "white sand 1016 seeds";
3. Improve the soil, pay attention to drainage, apply more organic fertilizer, sowing peanuts, 667 square meters of planting wood ash 50kg ~ 150kg, 12% calcium magnesium phosphate 20kg ~ 30kg, can promote robust growth of peanuts, improve disease resistance;
4. Chemical control
1 When sowing peanuts, the use of green-enjoying one or fulvic acid seed dressing can effectively prevent the occurrence of peanut bacterial wilt. The application method is to use 1 kg to 2 g per kg of seeds, or 2 g to 3 g of fulvic acid per kg of seeds. Mix well to sow, control effect up to 80% to 90%
2 In the peanut seedling stage or disease stage, spraying with sand fungus king or everywhere gold 1000 times to 1500 times liquid spraying, the control effect of more than 90%, when the disease is heavy 667 square meters using sand fungus king or everywhere gold 35g against 15kg ~ 20kg dilution Irrigation, the effect is excellent.
Second, peanut leaf spot
Peanut leaf spot, there are two kinds of brown spot and black spot. During the growth of peanuts, it is common and the mixing takes place on the same plant or even on the same leaf. Brown spot occurred earlier and black spot occurred later. The control measures were as follows:
1. Strengthen the management of the field, remove the stubble diseased plants immediately after the harvest, and eliminate the source of the infection.
2. Reasonable fertilization, increase calcium magnesium fertilizer and potash fertilizer, in order to improve the disease resistance of peanuts.
3. Chemical control can control the spread of diseases, maintain long green leaves for long-term and prolong photosynthesis time:
1 The use of sand fungus Wang 1500 times to 2000 times the liquid in the growing period of spraying 2 to 3 times, interval 15 days to 20 days, the control effect of up to 93%;
2 In the seedling period of 667 square meters with gold everywhere 0.5g water 15kg ~ 20kg, continuous spraying 3 to 4 times, each time interval 15 days to 20 days, the control effect of 95% or more, at the same time, can prevent other diseases occur.
In addition, the powerful anti-disease-increasing agents “Sand Kingâ€, “All Over Gold†and “Yellow Yeh Ching†have a certain preventive effect on the prevention of the occurrence of peanut virus disease. When the disease is controlled, such as bacterial wilt, leaf spot, etc., mixed spraying , Can enhance disease resistance, increase production more than 30%.
The fresh and natural taste is always attractive to people. When you are confused, drowsy and need to relax, if you take a few minutes to feel the aroma of the fruit, the situation will be completely different. As you know, blueberry flavor has always been popular with people. Therefore, we have developed and produced blueberry-flavored cigarette substitutes to help people feel the comfort of nature anytime, anywhere.
