Detailed Explanation of Three Fish Feed Formulas and Their Mixing Methods
(1) Grass carp feed formula (1) Rice bran 40%, wheat bran 38%, soybean cake 10%, fish meal 10%, yeast powder 2%. The feed conversion ratio of this formula is 1.9; if green fodder is added separately, the feed conversion ratio is 2.2. This formula was provided by the Pearl River Fisheries Research Institute. (2) Rice straw powder 80%, soybean cake 10%, rice bran 10%. This formula was provided by the Yangtze River Fisheries Research Institute, with a feed conversion ratio of 4.9. (3) Corn meal 70%, fish meal 10%, soybean cake powder 15%, wheat bran 5%. Its additives and binders are: sweet potato 12%

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

Detailed Explanation of the Rapid Cultivation Method for Standard (Tree-Form) Honeysuckle
Honeysuckle, as a raw material for pharmaceuticals, beverages, and beauty and cosmetic products, has long been in short supply on both domestic and international markets. Most regions of our country are suitable for its cultivation. At present, ground-covering shrub-type cultivation is mostly adopted in various places. In order to develop toward three-dimensional cultivation, make full use of space, increase light exposure, and improve its yield and quality; and also to provide a new tree species for roadside ornamental greening, the cultivation and development of standard (tree-form) honeysuckle has become an urgent task. For this reason, we carried out a series of studies on the cultivation techniques of standard (tree-form) honeysuckle in Pingyi County, the hometown of honeysuckle. Now

How does the Super Dry Rice 1 variety perform?
Super Dry Rice 1 is a new super-high-yield dry rice variety bred by the China National Rice Research Institute. Results from plantings in Hangzhou and Hainan show that this dry rice variety has strong stress resistance, high and stable yield, and above-average grain quality, with broad application prospects, especially when planted as an early crop (dry season) in Hainan and South China, where it has considerable yield-increasing potential and great value for development and promotion. The characteristics and key cultivation techniques of Super Dry Rice 1 are briefly introduced as follows: 1. Characteristics of Super Dry Rice 1. 1. Main agronomic traits. Super Dry Rice 1 demonstrated in the Hainan dry season

Functional features and uses of the artificial shrimp meat forming machine
In recent years, surimi products (fish balls, fish cakes, fish sausages, fish rolls, fish patties, etc.) have become one of the most popular aquatic foods on the dining tables of families, hotels and restaurants. With the continuous expansion of the surimi product consumer market, the production of surimi products has gradually moved from family workshop style to factory production, and processing different products requires different forming machines. This article introduces an artificial shrimp meat forming machine that turns low-value surimi into shrimp meat. The designed production capacity of the machine is 30-40kg/h, and the individual weight of the product shrimp meat is 16

Cotton struggling to open its bolls? Reforming the planting method is key
In recent years, with the continuous deepening of the breeding of new cotton varieties and the improvement of sowing and seedling-raising methods, as well as the increase in the degree of agricultural mechanization, the planting method of cotton fields has become extremely important for high cotton yields. In the era when conventional cotton varieties dominated, cotton sowing was mostly direct seeding, cotton planting density was relatively high, cotton row spacing was relatively small, and cotton fertilization was mostly broadcast application. After hybrid cotton was promoted and applied on a large scale, because the individual development of hybrid cotton is larger, cotton field density was continuously reduced, cotton row spacing was expanded, and cotton

What is the introduction performance of the early yellow flat peach? Detailed explanation of cultivation and management key points
The early yellow flat peach was bred by the Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences through hybridization using 8-21 as the female parent and a French flat peach as the male parent, and was named in 1997. It was introduced to Toutunhe Farm at the end of the last century. Through nearly ten years of trial planting observation, this variety is relatively suitable for the local natural conditions and can be developed and promoted in the **suburbs of towns along the economic belt on the northern slope of the Tianshan Mountains. 1) Overview of the introduction site. Toutunhe Farm is located in the western suburbs of Urumqi and belongs to the 12th Division of the XPCC. The soil is half sandy and half clay, and the soil pH is moderately acidic. It belongs to a mid-temperate semi-arid climate zone, with four distinct seasons,

How does 'Lübaoshi' pear perform in Zunhua, Hebei?
The 'Lübaoshi' pear was bred by the Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences by crossing 'Xinshiji' with 'Zaosu'. Zunhua City introduced the 'Lübaoshi' pear from the Zhengzhou Fruit Research Institute in 2003. Top-grafting was carried out in Xiafu Village, Xisanli Township, and the cultivar grafted over was 6-year-old 'Yantai' pear. 1. Test orchard conditions and management. The soil of the top-grafted orchard is sandy loam, with irrigation available. The level of management is moderate. In spring, bud grafting with wood was used, adopting multi-branch top-grafting, and the trees were in good condition at that time. The top-grafted 'Lübaoshi' pear occupied 1 row, 32 trees in total, and the grafting survival rate reached 97.7
