Autumn is the season where temperatures are unstable and change greatly. The impact on animals and plants is great. During this period, special attention should be paid to the use of five kinds of fodder for cattle and sheep.
First, Dew-grass began to cool in autumn, and dew drops often appeared on the leaves of grass in the early morning and early evening. Cows and sheep eat this kind of grass will cause rumen bloat disease. Therefore, in the morning, cattle and sheep are grazing in the morning to wait for the sun to rise, and after the dew has disappeared, they will go out and grazing. In the evening, they must return to the pasture before dew occurs.
Second, the soft skin on the corn on the corn flake is peeled off after harvest. Corn cobs are soft, soft and sweet, and cows and sheep love eating, especially when they are hungry, often swallowing whole pieces. There are also farmers who are busy with their farming activities. To save time, they are not short and do not mix grass. They are directly fed with whole pieces of corn on the soft skin to feed cattle and sheep. This is very dangerous. Because the soft skin of corn cobs is sweet, cattle and sheep like to eat, but it contains a lot of crude fiber, particularly strong toughness, not easy to chew and digest, gather in the valve in the stomach bow obstruction, a long time will ferment, corruption, gas production , And produce a large number of toxic substances, causing the body to die of acidosis.
3. After the harvest, the sorghum and corn two-seeded seedlings contain a large amount of hydrocyanic acid in the sorghum and corn seedlings that are harvested after the fall harvest. Hydrocyanic acid is a highly toxic substance that is easily poisoned by cattle and sheep. It is not possible to use this double-seedling as a forage for cattle and sheep, nor can it be used to grazing cattle and sheep in the land where there are two-seeded seedlings.
Fourth, the cream hit the leaves and stems of ramie Autumn season, the leaves and stems of ramie hit by the frost contain a toxin of ricinine, and the cows and sheep are vulnerable to poisoning after eating.
Fifth, semi-dry semi-humid sweet potato yak and sheep after a large number of feed intake, it is easy to suffer from intestinal obstruction disease (also known as constipation, cramps). Because sweet potatoes are harvested, their cockroaches have already aged, the crude fiber in the cocoon increases, and after a few days of sunlight, the crude fiber becomes softer and more flexible. After the cattle and sheep feed, these are flexible and not easy. Broken crude fibers entangled in the intestine, blocking in the large intestine and blocking in the small intestine. If the disease is not diagnosed and treated in time, it can easily cause death.
"Fuda" fruit trees work
Since July, the high temperature in our province has continued, especially the high-temperature and high-humidity climate that has been accompanied by more than a dozen days, which has caused serious threats to the normal growth of apple, kiwifruit, Portuguese, Portuguese, and other fruit trees. Especially in kiwi fruit, the fruits of the kiwifruit are softened by the sun, followed by Portuguese, apple and other fruit which have different degrees of sunburn. The high temperature also exacerbates the occurrence of fruit diseases such as fruit shrinking, bitter pit disease, and fruit cracking. The second is the growth restriction. As the evaporation of soil moisture and the transpiration of fruit trees increase sharply, the growth of new shoots, leaves and fruits is slowed or even stopped, which affects the accumulation of organic nutrients and the differentiation of flower buds, and adversely affects the production in the coming year. Third, a large number of pests and diseases occurred. High temperature and high humidity are the most favorable conditions for most pests and diseases. Current diseases are mainly brown spot, gray mold and anthrax, and downy mildew in grapes. The main insect pest is red spider.
In order to ensure this year's fruitful and high-quality fruit production in our province, we must grasp the following management tasks:
1. Irrigation irrigation volume should reach 70-80% of the maximum water holding capacity in the field, especially for kiwi fruit, and it should be ditched once every 7 days. Irrigation can be sprayed and cooled without irrigation, once every 3 days to reduce sunburn.
2. Fertilizer can use 0.3-0.5% potassium dihydrogen phosphate, urea, and amino acid fertilizer to increase the photosynthesis of leaves.
3, control of pests and diseases during this time, a large number of diseases occurred to the use of therapeutic agents based production of pesticides can be used for different diseases and corresponding drugs.
