The Causes and Prevention Measures of the "Vushou" Phenomenon in Spring Kidney Bean
"Fuchou" Phenomenon: After the first production peak of cowpea in production, the second production peak cannot be ushered in. This phenomenon usually occurs on the open days when it is produced in the open field, so it is called "Fuchei". Reasons: First, sowing too late. After the first production peak period, some flowering branches were extracted and there was not much spasm. The growth was inhibited and it was impossible to see the second peak of production. The second is that the first production peak consumes a large amount of nutrients, fertilizer and water are not added in time, resulting in dehydration and dehydration, premature aging of plants, can not send more new branches, the result will stop. Thirdly, during the process of plant growth, due to the lack of timely pruning and lack of collaterals, the basis for the secondary results was lacking.
