What are the causes of cotton abortive development and the remedial measures
Cotton abortive development occurs every year. So-called abortive development means that cotton has lost its normal reproductive function, that is, it only flowers but does not set bolls, or it flowers heavily but sets few bolls. The causes are first of all climatic factors, secondly the blind and indiscriminate introduction of cotton varieties, and thirdly cultivation methods that are incompatible with climate change. According to records, when the temperature exceeds 35°C, pollen development becomes deformed and normal pollination cannot occur; sustained drought then intensifies the shedding of squares and bolls. In addition, in mid-August some cotton areas experience a continuous week of rainy weather, which also makes it difficult for cotton to flower and pollinate normally.

What are the prospects for snake farming? An introduction to the development prospects of snake farming
Because snakes have significant economic value, many people, directly driven by profit, have taken up professional snake catching as a trade to gain substantial economic benefits.
