Taiwan Agricultural Research Institute cautiously sprays Bacillus thuringiensis; the Taiwan Agricultural Chemicals and Toxic Substances Research Institute formulates a pest sex pheromone blend to trap and kill adults, reducing damage from the Asian corn
In addition to breeding work, the Taiwan Agricultural Research Institute has another important task: seed preservation. When researchers at the Taiwan Agricultural Research Institute carry out seed preservation in corn fields, they always encounter serious corn borer problems. In the past, the insecticide chlorpyrifos was sprayed to prevent

How to formulate lactating sow feed scientifically
Sows bear very heavy responsibilities. Lactating sows in particular must not only supply the nutrients they need themselves, but also supply the breast milk on which newborn piglets depend for survival, growth and development. Moreover, lactating sows in the high-temperature season face an even more unfavorable living and production environment, and heat stress is a severe challenge for farrowing sows. Therefore, how to scientifically formulate the summer diet of lactating sows and strengthen feeding management should be a problem that pig producers must actively consider and focus on solving. Optimizing the formulation and raising the energy level should

Detailed Explanation of Key Technical Points for Soil Testing and Formulated Fertilization in Rice
I. Fertilization Principles 1. Soil testing and formulated fertilization for rice should follow the principles of determining yield target based on soil, determining fertilizer rate based on yield target, supplementing deficient nutrients, combining organic and inorganic fertilizers, and balanced application of nitrogen, phosphorus and potassium. First, soil testing is required. Soil testing is the prerequisite for soil testing and formulated fertilization; through analysis and determination of soil nutrients, the soil nutrient status and fertilizer supply capacity can be accurately grasped, providing a scientific basis for formulated fertilization. Second, a good formula must be prepared. The formula is the key to fertilization. On the basis of soil testing, according to soil characteristics, cultivation practices, crop nutrient requirements, production level and climate conditions,

How are pig immunization programs formulated? Mastering these key points is crucial
With the continuous development of the pig farming industry, the breed quality of pigs is gradually improving, and their numbers are also increasing; the pig farming industry has created relatively good economic benefits for the vast number of pig farmers. Entering the second half of 2002, the pig market rose steadily, with the selling price of fattening pigs at 6.40-6.80 yuan/kg: the selling price of commercial piglets at 12.00-13.50 yuan/kg: in the spring of 2004, pig prices reached their highest value in recent years, with the selling price of fattening pigs at 7.60-8.20 yuan/kg: the selling price of commercial piglets at 13.50-

How to formulate feed for pigs during lactation? Sharing practical formulation tips
Sows during lactation need large amounts of nutrients to support milk production. At peak lactation, the sow's milking capacity exceeds the nutrients she takes in through feed and the nutrients excreted in milk are greater, so the sow's body condition declines rapidly. Formulating high-quality, high-nutrient-density feed for lactating sows is the best way to resolve this contradiction. Feed Formula 1: Lactation Feed Formula 1 in Table 4-3 avoids as much as possible the use of bulky feeds such as alfalfa and rice hull bran. In the design of lactation feed formulas, unknown nutritional factors appear less important

How to formulate feed for pigs during lactation in a scientific way
Sows need large amounts of nutrients during lactation to support milk production. At peak lactation, a sow's milk production capacity exceeds the nutrients she takes in through feed and the nutrients lost through milk, so her body condition declines rapidly. Preparing high-quality, high-nutrient-density feed for lactating sows is the best way to resolve this contradiction. Feed Formula 1: Lactation Feed Formula 1 in Table 4-3 avoids as much as possible the use of bulky feeds such as alfalfa and rice hull bran. In the design of lactation feed formulas, unknown nutritional factors appear less important, and this formula uses high-energy feed corn and high-protein feeds such as fish meal and soybean meal as much as possible, so that the volume of the compound feed is reduced as much as possible and the nutrient concentration is increased as much as possible. The formula also uses synthetic amino acids to further fortify the first limiting amino acid and improve the utilization efficiency of feed protein. To ensure milk quality, the amounts of micro-ingredients in the formula remain unchanged from those in gestation feed. Compound feed produced with this formula, when used to feed high-yielding sows nursing about 10-15 piglets, can achieve very ideal lactation and nursing results.

How to formulate ecological feed? Key technical points explained in detail
1. Wean in time and group reasonably. After lambs reach 2 to 3 months of age, separate the mother from the lambs for weaning. This allows the ewes' condition to recover quickly, achieving the goals of early estrus, early mating, and high yield with multiple births, while also promptly training the lambs' ability to live independently; for sheep farming, after weaning, group the lambs reasonably by sex, size, and strength in separate pens to prevent the strong from becoming stronger and the weak from becoming weaker, which would affect the overall development level and uniformity. 2. Mate at the right time to improve the reproduction rate. Mating too early will affect the ewe's own growth

How to carry out soil testing and formulated fertilization for mango
The flowering and fruit-setting period of mango is an extremely critical period in mango production management. The management measures during its flowering and fruit-setting period include the following aspects: 1. Training of flowering branches and shoots. About 2 months before flower bud differentiation, remove overly dense branches, shaded weak branches, and diseased and pest-infested branches, leaving only 1-2 shoots per branch, which can increase the tree canopy's...

Can soil testing and formulated fertilization be used for cherry trees?
How should fertilization be done for cherries to achieve high yield? Please advise. Cherry trees have a short fruit growth period and are characterized by rapid, concentrated nutrient demand. Fertilization should be based on tree age, tree vigor, soil fertility and the nutrient requirements of the variety, supplying the various nutrient elements needed for cherry growth and development in a timely and appropriate manner, so as to achieve the goals of strong trees, high quality and high yield....
