Potato, Huaishan and other rhizome and tuber crops to increase yield and disease resistance

 

1. Common problems during sowing-tuber formation: weak growth, dead seedlings, fewer tubers, and more diseases

 

Solution: flushing: 1-2 kg / mu, 1-2 times after emergence-tuber formation period, about 1,000 times water, once every 10-15 days, supplement phosphate and calcium, increase seedling strength, promote Grow and promote tuber formation; Spraying: 100-1000 g / mu, spraying with water 50-500 times (Note: if the amount of water spray is small, the spraying concentration should be controlled within the recommended range), continuous spraying during tuber formation 1-2 times, once every 10 days, the leaves are thick green and the number of tubers is significantly increased;

 

2. Common problems during tuber expansion: small tubers, low yield, early yellow leaf senescence, low yield, poor quality, intolerance to storage and transportation, and many diseases

 

Solution: rushing: 2-3 kg / mu, 1-2 times during tuber expansion, once every 10-15 days, healthy stems and leaves, no premature aging, rapid tuber expansion, high yield; spraying: 100- 1000 g / mu, spray with water 50-500 times (note: if the amount of water spray is small, the spray concentration should be controlled within the recommended range), two sprays during the tuber expansion period, about once every 10 days, large Large number of potatoes, increasing yield;

 

Feedback from farmers: Guangdong Yudong Lin Yuchun I sprayed and sprayed, the effect is quite good, the leaves are thick, the gloss is good, the health is strong, the disease resistance is strong, the stalks are strong, and the plot of the compound fertilizer is not large. There are yellow leaves.

 

 Guangdong Huidong has sprayed and drenched potatoes this year. The leaves are good, the stems are strong, and the tubers swell particularly quickly. It is found that the number of large potatoes used has increased during the harvest. Yield per mu has increased by 835 kg, an increase of 19%. Potato 1.jpg

 

Xue Guangshi, Wenxi County, Shanxi, China. The sweet potatoes were sprayed and sprayed after emergence. The emergence was neat and the leaves were green. The number of used sweet potatoes was large, the size was large, and the yield increase was too obvious!
