Scientific control methods for the first-generation Asiatic rice borer (Chilo suppressalis) in rice
According to surveys conducted across Hubei Province, the overwintering mortality rate of the Asiatic rice borer this year was higher than last year, and the post-winter population base was lower than last year but still relatively high. In addition, suitable climate conditions and the expansion of high-quality rice varieties are both favorable to the occurrence and damage of rice stem borers, and the first-generation Asiatic rice borer will show a major outbreak trend in the rice-growing areas of our province, making the control situation still severe. In response to this severe situation, all localities should strengthen leadership, raise awareness, actively organize control efforts, and quickly launch a campaign to wrest grain from the pests to ensure the safety of grain production. 1. Recognize the situation clearly and strengthen organizational leadership. Last winter, our province suffered freezing ice and

Rice gene design breeding: scientists cultivate new varieties
The aroma of rice is richer, like fruit, with higher iron and zinc content, so there is no need to supplement other nutrients; all of this can be achieved through molecular design of rice genes. Recently, the author learned from the "Crop Molecular Design and Innovation" symposium that China is currently building a large bioinformatics infrastructure platform to ensure that high-quality genes are "hit every time." Zhu Yingguo, an academician of the Chinese Academy of Engineering, said that taking rice as an example, japonica rice with a soft and glutinous texture is more favored, and people also hope that rice aroma will be richer or have special aromas such as "fruity" notes. Moreover,

How Should Potatoes Be Stored? A Full Analysis of Scientific Preservation Techniques
How to scientifically store fresh potatoes for seed, food and processing use is a key link in extending the potato industry chain. Through scientific storage, market supply and demand can be regulated and value can be increased by 20% to 30%. Through in-depth investigation and research and production practice, the author discusses the current potato storage situation in Weichang County, the existing problems and scientific storage methods. 1. Current potato storage situation in Weichang Although farmers in Weichang have the habit of storing potatoes and have accumulated rich storage experience, there are also many

Detailed Explanation of Key Technical Points for Scientific Application of Fishery Drugs
Fishery drugs are all substances used to prevent, control and treat diseases, pests and harm of aquatic animals and plants, promote healthy growth of cultured species, enhance the body's disease resistance and improve the quality of aquaculture water. Here we specifically introduce several correct medication methods for the prevention and treatment of aquatic animal diseases: 1. Apply drugs according to the disease. There are many varieties of fishery drugs, and their physical and chemical properties differ. Therefore, before using fishery drugs, the main diseases and pathogens of the cultured prevention and treatment targets must first be accurately diagnosed, a treatment plan must be made, and then a suitable drug variety must be selected for targeted treatment; otherwise, it will not only fail

Scientific Feeding Methods and Technical Key Points for Growing Sheep
Whether the feeding of growing sheep is reasonable plays a decisive role in body conformation and growth rate. Improper feeding can cause sheep to be too fat, too thin, or experience stunted growth at a certain stage, resulting in undesirable conformations such as long legs, short body, and pendulous belly. Formula for growing sheep concentrate supplement Feed type Roughage type High-quality hay type Corn silage type Dry corn stalk type (%) (%) (%) Corn 60.00 58.50 58.50 Wheat bran 15

How to fertilize rice? Mastering scientific fertilization methods is key
Use organic fertilizer together with chemical fertilizer. Organic fertilizer is rich in organic matter, can build up soil fertility, provide a variety of nutrients, and also supply compounds with auxin- and hormone-like properties. Applying organic fertilizer helps maintain the nitrogen reserves in rice paddy soil. Organic fertilizer releases nutrients slowly, while chemical fertilizers are mostly quick-acting fertilizers that supply nutrients rapidly; using the two together makes the nutrient supply relatively steady. The organic acids and humic acids in organic fertilizer can bind with iron and aluminum in the soil, reducing the fixation of phosphate fertilizer by the soil and increasing the amount of available phosphorus and the

A Comprehensive Guide to Scientific Control Methods for Soybean Aphids
Soybean aphids are commonly known as "ni chong" (greasy bugs) or "mi chong" (honey bugs). They mostly gather on the growing points, top leaves and backs of young tender leaves of soybean plants, piercing and sucking sap to cause damage. This results in leaf curling, plant stunting and reduced yield, and they can also transmit viral diseases, causing yield loss and quality decline. This pest begins to appear in soybean fields in mid-to-late June, and causes severe damage during hot, dry weather. Soybean aphids have a very strong reproductive capacity; a single female can produce 50-60 offspring, and under suitable conditions, young aphids can give birth after about 4-5 days, and can reproduce 15

How to Care for Feverish Sick Pigs? A Detailed Guide to Scientific Care Methods
The normal body temperature of pigs is 38°C-40°C; if it persistently exceeds 40°C, it is fever. Prolonged continuous high fever accelerates the body's catabolism, disrupts digestive function, lowers resistance, and can even cause coma or heart failure. The treatment principles for feverish sick pigs are as follows: immediately isolate feverish sick pigs, and thoroughly disinfect the contaminated environment. Before the cause is identified, as long as the fever is not excessively high, generally do not use antipyretic drugs at will. While using antibacterial drugs, attention should be paid to supplementing nutrients.

How to Scientifically Choose Rice Varieties for Planting
How to scientifically choose rice varieties for planting should follow these principles: (1) Certified varieties with strong resistance. (2) In the same village or town, large-scale planting of a single variety should be avoided; 3-4 varieties should be mainly promoted and planted in combination. (3) Since this year's climatic conditions are not very favorable, varieties with a slightly earlier maturity period should be chosen. (4) Choose varieties sold by legitimate manufacturers. It is best to buy seeds from the breeding unit, because the breeding unit understands the characteristics of the varieties and the suitable regions. The seed purity is relatively good,

Detailed Guide to Potato Storage Methods: Teaching You How to Store Scientifically
I. Chemical and Physiological Changes During Storage. When potatoes are harvested, the tubers generally contain about 75% moisture. During storage, they have very strict requirements for temperature, humidity, light and air conditions. If these are not adjusted properly, they will cause adverse changes in physiological state and chemical composition. During storage, the physiological and chemical composition of potatoes is constantly changing. With changes in temperature, humidity and light, their respiration intensity changes accordingly. Due to respiration, weight can be reduced by 6.5-11%. If maturity is insufficient, nitrogen fertilizer is excessive, or potassium chloride alone is used, the weight loss will be greater.
