  • Detailed Explanation of Soybean Cultivation Technology with Film Mulching Between Rows on Wide Ridges

    Heilongjiang Province is China's main soybean production area, with its planting area accounting for 7% of the national total and its current total output accounting for 11% of the national total. In the course of soybean production development, the Heilongjiang Reclamation Area has vigorously promoted scientific and technological innovation, resulting in a relatively large increase in soybean yield per unit area and total output. From 2001 to 2005, the average yield per hectare reached 2531.7 kg; in 2005, the average soybean yield per mu reached 178 kg, reaching or approaching the soybean yields of advanced countries worldwide. Soybean cultivation technology with film mulching between rows on wide ridges

  • What is the relationship between the farming of the four major Chinese carps and meteorological conditions?

    Fish live in water, but they are also closely related to meteorological conditions. Temperature: fish are ectothermic animals, and the water temperature is their body temperature. The water temperature directly affects their life metabolism. The suitable temperature range is 10 to 33°C, and the optimal temperature is 25 to 30°C. Below 10°C they begin to hibernate. At 10 to 15°C they begin to feed and grow slowly. At 15 to 20°C their appetite increases and they grow faster. At 20 to 30°C they grow fastest. Above 30°C their growth slows again. Therefore, when feeding, pay attention to

  • How to Tell the Difference Between True Colds and False Colds in Dogs

  • What is the relationship between yellow fat pork and feed? An analysis of the causes

    Yellow fat pork, also known as yellow rind pork, refers to pork carcass fat that is brown or yellow, with the internal organs normal and unchanged and no off-odor, and it is generally believed to be caused by feed. Yellow fat pork is different from jaundiced pork; jaundiced pork is caused by disease, resulting from blocked bile excretion. In jaundiced pork, not only does the fat turn yellow, but the skin, mucous membranes, joint capsule fluid, tissue fluid, vascular intima, serosa, tendons, etc. all appear yellow, and the internal organs also show pathological changes. Yellow fat pork fades or loses its yellow color after hanging for 24 hours, whereas the yellow color of jaundiced pork does not fade. Yellow fat pork is mostly caused by feeding pigs fishmeal, fish oil

  • What is the difference between the two rice diseases? Explained clearly in one article

    In recent years, bacterial brown spot of rice has shown a trend of relatively severe occurrence in some rice areas of our province. Most farmers mistakenly treat this disease as rice blast, which both increases costs and fails to achieve good results. For this reason, the two diseases are specifically distinguished below. 1. Symptoms. The symptoms of bacterial brown spot of rice are that reddish-brown small spots first appear on the upper leaves of the rice starting from the leaf tip and leaf edge, then expand into spindle-shaped, long oval, or irregular strip-like streaks, gradually spreading to the entire leaf, causing local necrosis of the leaf, with no bacterial ooze visible

  • What is the difference between the potato ladybird beetle and the 28-spotted ladybird beetle?

    The potato ladybird beetle and the eggplant 28-spotted ladybird beetle are very similar in morphology. As soon as the potato sprouts, adults and larvae gather on vigorous plants to feed on the leaves and cause damage, overwintering as adults. Around April, the overwintered adults lay eggs in the field, and they emerge in July. In spring-planted areas, there is 1 generation per year. The larvae and adults of the 28-spotted ladybird beetle damage the leaves of vegetables such as eggplant, potato, tomato and cucumber, causing wilting. The larvae live on the underside of leaves. In warm regions, the adults have 2 to 3 generations per year, overwinter as adults, and generations overlap. After overwintering, the adults gather

  • What are the differences between Panax notoginseng and Anredera cordifolia
