What is the application ratio of special fertilizer for cotton drip-irrigated fields?
I. Total fertilizer application for cotton In high-latitude marginally suitable cotton areas, for a seed cotton yield of 300-380 kg, 70-80 kg of natural fertilizer is needed, equivalent to 160-180 kg of standard fertilizer. This achieves "a jin of fertilizer for a jin of cotton." Applying 1 kg of standard fertilizer can produce 1 kg of lint cotton. Soil test results and cotton plant nutrient diagnosis in Regiment 137 generally show zinc deficiency; applying 1-2 kg of zinc fertilizer in autumn increases yield by 5%-10%. For plots with abundant potassium according to test results, potassium fertilizer application is 5-10 kg, especially

Analysis of the Application of the Trellis Cultivation Model in Pear Orchard Renovation
Korla fragrant pear is one of the specialty fruits of the Aksu region. In 2003, due to a rare continuous low temperature in spring, 621 hectares of fragrant pear trees were killed by freezing, and due to natural factors such as wind damage and fruit drop during the flowering period, the fruiting area of fragrant pear decreased by 1933 hectares, with direct losses reaching 115 million yuan. The traditional frost prevention measures previously used in pear orchards, such as smoking and windbreak barriers, could not withstand sudden severe weather, making it particularly urgent to solve the frost and wind damage problems facing fragrant pear. The trellis cultivation model involves surrounding the pear orchard

Application Technology of Mepiquat Chloride for the New Large-Boll Cotton Variety Shuofeng No. 9
Characteristics and traits: This variety was developed from the original Shuofeng No. 9 through purification and rejuvenation selection. The plant is tall, with thick and hard stems, a loose plant type, and relatively long fruiting branches with few hairs. The leaves are large and dark green, the bolls are large, long-oval in shape. It emerges well, with uniform seedlings, vigorous growth in the early and mid stages, and growth stabilizing in the late stage, with good uniformity. The first fruiting branch node is low, boll setting is good, boll opening is full and smooth, easy to pick, the pre-frost boll rate is 91.0%, fiber length is 31.1 mm, fiber quality is excellent, making it a high-quality cotton variety. The growth period is 125 days, plant height 110-130 cm. Comprehensive traits are stable, resistant to

Detailed Explanation and Application of the New Muskmelon-Rice Multiple Cropping Technique
I. First Crop Muskmelon 1. Seed selection and land preparation: Choose high-yield, high-quality muskmelon varieties with a growing period of about 90 days, such as Chaozhao Tangwang and Hongchengcui No. 1. Before the ground freezes the previous year, plow the paddy field well, harrow, press and form ridges with a ridge spacing of 50-60 cm, and press firmly to preserve soil moisture. Along with land preparation, apply 5000 kg of high-quality farmyard manure per mu. 2. Seedling raising and transplanting: Soak seeds to promote germination in late February, raise seedlings in a greenhouse in late February to early March. You may use seedbed seedling raising followed by pricking out into seedling bowls, or directly raise seedlings in seedling bowls. For planting melons in the main field, transplant the melon seedlings into the main field before April 15.

Application Methods of Lime in Edible Mushroom Production
Lime has a significant disinfection and sterilization effect and is also rich in calcium, giving it a wide range of uses in edible mushroom production. 1. Application on the site: Clear the weeds around the site, spread a layer of lime powder, then clean the cultivation room thoroughly, spray conventional insecticide, and spread another layer of lime powder. This can kill some contaminating microorganisms and reduce the contamination baseline, especially bacterial contamination, and can also prevent pests such as slugs from invading the site and causing damage. 2. Application in the substrate: Most edible mushrooms can grow normally in a slightly alkaline

Key Technical Points and Application Methods of Wheat Straw and Wheat Chaff Mulching
Wheat straw and wheat chaff mulching involves evenly spreading wheat straw or wheat chaff around autumn crops or between rows to form a certain mulch layer, with an appropriate amount of soil pressed onto it in spots, so as to mulch and preserve soil moisture. For wheat straw and wheat chaff mulching, it is necessary to grasp the timing and mulching amount well, and to apply chemical fertilizers reasonably and according to other such principles. 1. Timing. The relatively suitable mulching time is from late June to early to mid-July. Too early makes it easy to press down the seedlings, while too late means the crop plants are tall and difficult to work with. After mulching, if there is no rain or insufficient rainfall, it will affect the rotting and decomposition of the straw, and the effect will be poor, so watering should be done in time. It can also be done at

Detailed Explanation of Rhododendron Cultivation Techniques and Landscape Application
China has a long history of rhododendron cultivation, with records of artificial cultivation dating back to the Han Dynasty. In the Tang Dynasty, rhododendrons began to be used in private gardens, and because of their graceful plant form and brilliant flower colors, they were deeply loved by people. Rhododendron generally refers to plants of the genus Rhododendron in the family Ericaceae, with about 960 species worldwide. China is the birthplace and distribution center of rhododendrons, with about 542 species, mainly distributed in the Hengduan Mountains area of the three provinces and regions of Southwest China, Yunnan, Tibet and Sichuan.

Application of Artificially Hatched Artemia in Industrialized Cultivation of Yellow Catfish Fry
1. Wide-ridge double-row planting method: This method transplants rice seedlings in a sequence of 6 cun, 12 cun, 6 cun. Its advantages: First, the total number of hills per mu (16,000 hills) is slightly less than that of monoculture rice, but yield increases through ventilation and light penetration; Second, it provides more than 7 hours of light daily, raises water temperature, and allows plankton to reproduce and grow rapidly, creating good conditions for providing natural food organisms for yellow catfish; Third, it broadens the activity space for yellow catfish, enables large-scale pest elimination, and fish feces serve as fertilizer, increasing rice yield. 2. Rice management: Rice cultivation management strictly follows
