Occurrence and Control of Rice Stirrups

Types and Symptoms of Paddy Rice Seedlings The rice seedlings grew abnormally after transplanting, which showed that the rice plants clustered and the leaves became smaller and smaller. The leaves showed auburn spots or reddish red; the growth was stagnant, the tillers rarely occurred, and the root growth was blocked. Phenomenon, known as sit-in, some people call it "Jingmiao" or "fire wind."
Cold damage type: Mostly occur in muddy fields, deep foot fields, cold flood fields, and back-yin fields. Such fields are flooded for a long time and the temperature of mud is low. When encountering continuous low temperature and low temperature, the occurrence of seedlings is increased. The main manifestations are delayed greening after planting, impeded growth, no new roots, roots aging, softening, brown or black, with many irregular brown spots on the tip.
The lack of type: lack of a certain kind of nutrient elements lead to the physiological metabolism of seedlings caused by the lack of phosphorus, potassium, zinc and so on. Symptoms are as follows: P-deficit rice seedlings have few new roots, the roots are thin and brownish black, and the armpits are clustered with dark brown leaves. The potassium-deficient rice roots grow weakly, the leaves are short, dark green, and the old leaves have auburn spots. The leaves are easily broken and the main veins are yellow; the zinc-deficient seedlings are not easy to pull out of the leaf curls, and the leaves appear chlorotic stripes at the seedling stage, and the leaves are red and the roots are short and less.
Poisonous type: Mostly occur in long-term flooded deep foot fields, poor soil permeability in the rush tank fields, muddy fields, and large fertilizer fields behind houses. This type of field contains a large amount of unrefined organic fertilizer. Because of the decomposition of organic matter or the low topography and accumulation of water in paddy fields, large amounts of reducing substances are accumulated in the soil. Toxic roots are poisoned by toxic substances such as hydrogen sulfide, organic acids, divalent iron, and methane. Root respiratory and nutrient absorption. Symptoms mainly manifested as blackening of the roots.
In addition, due to improper cultivation measures may also cause rice to sit, such as deep-water planting, planting seedlings planted too deep, planting thin and weak and so on. Different types of rice squats have different symptoms and causes. However, cold, poisonous, and nutrient-deficient sit-ins often affect each other and cause and cause each other. For example, low temperature and poisoning not only weakened the resilience and root activity of the seedlings, but also affected the activation of soil nutrients and the absorption of roots, which in turn led to plant nutrient deficiency.
Prevention and control measures should be based on the measures adopted by Tianchang, prevention, and comprehensive prevention and control. 1 Nurture broth to enhance seedling resistance.
2 timely planting, improve the quality of planting. To plant a loquat should not be too early and easy to sit on the plots of the plot, and the age of the loquats can be appropriately extended. Shallow-water planting measures should be implemented. For deep foot fields and muddy fields, pay attention to soil replanting and planting or planting muddy loquats. For deep-seedling and mud-ditch fields that are used to sit for a long time, we should vigorously promote semi-dry cultivation techniques. Improve the soil structure and water, heat, and gas conditions, which is an effective way to prevent and control this kind of field block.
3 Do a good job in the irrigation and drainage system of rice fields. So that every paddy field can be timely irrigation, drainage thoroughly, in order to lead to cold water and cold water, lower groundwater level, improve soil permeability, increase ground temperature, eliminate poisons.
4 Paddy fields that sat every year should implement paddy-upland rotations and replant rice after 1 to 2 years of drought.
5 The remedial measures should be taken as soon as possible for the plots that have taken place, in order to promote the early emergence of the seedlings and reduce the damage. First, conduct a field survey to find out the cause of the disease. For deep-rooted muddy fields, cold-sweeping fields, and large fertilizer fields, it is necessary to immediately drain water, properly dry the fields, draw up water, lower the groundwater level, improve soil permeability, increase mud temperature, eliminate poisons, and reduce poisoning. At the same time, black and white ash (grasswood ash: lime = 1:1.5) was used to neutralize toxins such as organic acids.
The shortage of raw materials should be supplemented in a timely manner with nutrient-supplying fertilizers or spraying Tianda 2116 or Zhuangmiaoling or grain-based remediation. The above-mentioned rice diseases and low-temperature chilling damage caused by the lack of Vitamins And Minerals caused by physiological diseases, the best method of prevention and treatment is to use Tianda 2116 Zhuang Miaoling + Tianda hymexazol.
