High-yield cultivation techniques for plastic-mulched garlic, plastic-mulched watermelon, and cotton
Suwan Town in Chaohu City is a major cotton-growing town. In order to adjust the cropping structure of cotton fields and increase the multiple cropping index and economic returns, after several years of practice, an efficient intercropping and relay cropping model of plastic-mulched garlic, plastic-mulched watermelon, and cotton has been developed. It not only gives good economic returns, but can also build soil fertility and realize the combination of using the land and maintaining the land; at the same time, it can change the ecological environment and reduce the occurrence of pests, diseases, and weeds. 1. Variety selection. For garlic, use the early-maturing variety Ershui Zao; for watermelon, choose early-maturing superior varieties such as Beimi No. 3, Huami No. 8, and Zhengza No. 7; for cotton, choose Guokangmian No. 1 supplied by the Cotton Research Institute of CAAS,

Introduction to the High-Yield Garlic Variety Huanong No. 1
Huanong No. 1 garlic is a high-yield garlic variety bred by the Zhongke Huanong International Agricultural Development Research Center of the Chinese Academy of Agricultural Sciences. In 2007, expert yield assessment and acceptance showed that the demonstration field produced 5800 jin of garlic bulbs per mu. This variety has a well-developed root system, strong growth vigor, thick and sturdy stems, and broad, thick, dark green leaves, with strong cold resistance and disease resistance. It has high garlic bolt yield, and the garlic bolts are tender and of excellent quality. The garlic bulbs are large, uniform and attractive, with more than 90% having a diameter between 6 and 8 cm, giving excellent marketability; the bulb skin is thick, the cloves do not scatter, and the bulbs tolerate storage and transport, with excellent quality. It is a good

High-yield and high-quality cultivation techniques for garlic in the Hangzhou area
Garlic is a plant of the genus Allium in the family Amaryllidaceae (Liliaceae) and is an important pungent vegetable. At present, the garlic planting area in China is gradually expanding. In addition to the main producing areas of Shandong Province, Jiangsu Province and Henan Province, it is also widely cultivated in other regions, among which the Yangtze River basin is also an important garlic producing area. Due to differences in climatic conditions, garlic cultivation techniques in each region have their own characteristics, and the cultivation and management methods also differ from those in other regions. The high-quality and high-yield cultivation techniques for garlic in the Hangzhou area are introduced as follows. 1 Site selection and land preparation Garlic likes fertilizer and water, and its root

Winter control of rice pests and diseases can yield twice the result with half the effort
In winter, rice pests and diseases are in a dormant state: pests stop feeding and pathogens stop infecting. If farmers seize this favorable opportunity to carry out control, they can achieve twice the result with half the effort. 1. Dispose of diseased rice straw. Diseased straw is the overwintering site for the pathogens of rice bacterial leaf streak, bacterial blight, rice blast and many other diseases, and is the main source of infection the following year. Before the end of March, farmers can compost diseased straw at high temperature, or process it as feed or fuel, which can greatly reduce the number of pathogens. For diseased rice straw that cannot be fully processed before the end of March,

High-yield method for fish-lotus polyculture in grid ponds
The grid pond fish-lotus polyculture technique involves partitioning a hardened lotus pond into small grids of 2 sq m to 4 sq m using roof tiles, hard boards, etc., and planting lotus within the grids. The average yield per mu of water surface is 0.5 wan kg of lotus root and 400 kg to 450 kg of fish, with a net benefit of over 10,000 yuan per mu. This technique can utilize waste pits, wasteland, river beach land, and scattered marginal land to build grid ponds for fish-lotus polyculture. It features small investment, low cost, quick results, and high efficiency, making it suitable for vigorous development by thousands of rural households. It can both increase economic income

Tea plant breeding yield identification methods and technical key points
A method for measuring the breeding yield of tea plants (individuals, lines or strains). The direct measurement of yield is calculated based on the harvested amount of buds and leaves per unit land area of the tea plant. ① Annual picking calculation method: according to a certain picking standard, pick in stages and batches by plant or plot, then separately count the total yield of each season within a year. In black tea and green tea regions, picking is generally done at the standard of one bud and two or three leaves; in dark tea regions and oolong tea regions, picking is done at the standard of 4-5 leaves at the resting shoot. In the later stages of breeding, yield performance must be measured to identify production potential.

Seven methods of applying nutrient solutions to increase oyster mushroom yields
1. Sucrose and calcium carbonate phosphate mixed solution: sucrose 1%, calcium carbonate 1%, potassium dihydrogen phosphate 0.1%. Use when the mycelium has covered the mushroom bed and before fruiting bodies appear. 2. Urea and citric acid mixed solution: urea 0.5%, citric acid 0.1%, adjust pH to 7 with sodium hydroxide. Use after the first flush of mushrooms is harvested. Using it after the second flush is not effective and instead hinders oyster mushroom growth. 3. Sugar, urea and citric acid mixed solution: sucrose, citric acid and urea 1% each, adjust pH to 7. Same

High-yield cultivation method of cutting oyster mushroom blocks into pieces, standing them upright and covering with soil
Mushroom farmers in Dongkan Town, Binhai County, Jiangsu Province, through years of oyster mushroom cultivation practice, worked out the six-character high-yield formula for oyster mushrooms of "cutting into blocks, standing upright, covering with soil", which increased the oyster mushroom yield per mu by more than 2000 jin compared with the past, with an increase rate of about 30%, and at the same time, production costs dropped greatly. Their high-yield experience mainly consists of three steps: "cutting into blocks, standing upright, covering with soil". The so-called "cutting into blocks" means that at the end of harvesting the second flush of mushrooms in furrow-bed cultivation, the dead mushrooms, stipes and the like remaining on the bed surface are cleaned up, and a sharp knife is used to cut the cultivation substrate into multiple pieces of about 50 cm

Four key measures for high-yield cultivation of oyster mushrooms
Supplementing nutrient solution: After harvesting the first flush of mushrooms, soak the mushroom bags in nutrient water with 0.1% urea and 3% white sugar for about 10 hours, allowing them to absorb a large amount of water, and the second flush will form quickly; then use a water injector to inject nutrient solution (vitamin B1, 20 mg, magnesium sulfate 20 g, boric acid 5 g, zinc sulfate 10 g, urea 25 g, cold boiled water 50 kg), reduce humidity and keep warm for 7 days, and the second flush will grow smoothly. Alternatively, break the mushroom skin at both ends of the bag once, place upside down on the ground, and irrigate with sufficient nutrient solution water (vitamin B

Semi-underground three-dimensional cultivation of oyster mushrooms yields high output and good returns
Semi-underground three-dimensional bed-frame cultivation of oyster mushrooms is a new approach explored in recent years to achieve high yields and improve economic returns. According to trials, on an area of 20 sq m, with 2000 kg of substrate, the annual output of oyster mushrooms is about 2500 kg, with a biological efficiency of over 120%. The key technical points are as follows: 1. Building the greenhouse: first dig a pit 1.8 m to 2 m deep and 4 m to 5 m wide, with the length determined as needed, and place the three-dimensional bed frames inside. On top, use bamboo poles and plastic film to build an arched shed, pack the surrounding edges firmly with soil, and cover with straw mats. Leave ventilation openings of about 30 square cm on all four sides, east, west, north and south, and build a small door on the west side for workers to enter and exit.
