Key Technical Points for High-Yield and High-Quality Cultivation of Garlic with Plastic Mulching
Garlic is currently one of the main cultivated vegetables in the Laixi area, with a cultivation area of over 200,000 mu over the years. To increase the economic income of local garlic farmers, since 1998 we have conducted experimental research and extension of large-scale high-yield and high-quality garlic cultivation technology with plastic mulching. In the demonstration park, the average yield per mu is 1,000 kg of garlic scapes and 1,000 kg of garlic bulbs, with the highest yield per mu exceeding 1,250 kg. The garlic scapes produced are green and tender, and the garlic bulbs are plump, white, strongly pungent, and highly viscous, with strong market competitiveness. They are exported in large quantities, and the economic benefits are considerable. The main techniques are summarized below.

Frequently Asked Questions About Fertilizing and Weeding Cotton Under Plastic Mulch
Recently, Ding Libang, a 75-year-old farmer from Shuqiao Village, Wuluo Town, Yunmeng County, Hubei Province, called me to ask whether he could switch from raising seedlings in nutrient pots and transplanting them to cultivation under plastic mulch this year. Here is my answer. Q: Can chicken manure be used as a base fertilizer for cotton under plastic mulch? A: When using chicken manure as a base fertilizer, several points must be noted: first, the chicken manure must be fully decomposed; second, it must be applied early, before the mulch is laid; third, the application rate must not be less than 1500 kg per mu; fourth, because chicken manure contains a certain amount of weed seeds, attention must be paid

Method for ridge cultivation of Gastrodia elata in plastic greenhouses
Cultivating Gastrodia elata in ridges inside plastic greenhouses can be done on either a large or small scale, with low investment, high returns, and savings in labor, effort, and arable land. It requires no fertilizer, no pesticide spraying, and no weeding, and delivers significant economic benefits. The technique is described below: 1. Site selection: It is advisable to choose a shady slope or a gentle slope with half shade and half sun, sandy soil with good permeability, and slightly acidic or neutral soil with a pH of 5.5-6.0 for building the site. 2. Greenhouse construction: Follow the construction method for vegetable greenhouses, facing north and south, with the size determined by the scale of Gastrodia elata cultivation, generally 8 m wide and the length depending on the terrain

Method for making shiitake mushroom (Lentinula edodes) spawn in plastic bags
The method for making spawn using 17 cm × 33 cm polypropylene plastic bags has already been described in the production of spawn for block cultivation. In recent years, substitute-material shiitake mushroom production has developed rapidly in northern China. Due to differences in climatic conditions and other factors, most northern regions adopt large-bag cultivation. Since large-bag cultivation also uses plastic bags as containers for spawn production, its operational precautions and technical key points are the same, but some specific operations differ. Large-bag cultivation uses low-pressure high-density polyethylene plastic tube bags, 0.5-0.6 mm thick and 22-25

Method and Technology for Processing Waste Silk into Plastic Wrap
The "National Institute of Agrobiological Sciences, Silk and Insect Agricultural Technology Research Institute of Japan" conducted "Research on the Development of Silk Fibrillation and Silk Paper for Packaging." Their fruit and vegetable plastic wrap made from silk as a raw material did indeed achieve certain results. Using inferior cocoons that cannot be reeled or waste silk as raw materials, through processes such as cocoon boiling and reduction treatment, they manually stretched and expanded the cocoon layers into silk strands, then after careful beating, cut the silk fibers to make silk pulp equivalent to papermaking raw material. This was mixed in equal halves with specially made regenerated cellulose, and processed in the manner of washi (Japanese paper) to produce

Detailed Explanation of Agronomic Supporting Techniques for Drip Irrigation Under Plastic Mulch in Cotton
Drip irrigation under plastic mulch is a technique that combines drip irrigation technology with plastic film mulching cultivation technology. Water is supplied through a controllable pipeline system; after water and fertilizer are mixed, they are delivered drop by drop evenly, at set times and in set amounts, moistening the crop root development zone and always keeping the root-zone soil loose and at optimal moisture. It reduces evaporation between crops and improves water use efficiency. 1. Irrigation regime. For subsurface drip irrigation, total water use was 175.48 million cubic meters. Dripping was done 9 times. For precision drip irrigation, total water use was 177.84 million cubic meters. Dripping

Detailed Explanation of Key Points of Cotton Cultivation Technology with Drip Irrigation under Plastic Film
I. Pre-sowing Preparation 1. Variety Selection: According to climate and soil conditions, select varieties with a growth period of about 130 days, resistance to Fusarium and Verticillium wilt; compact plant type, short fruiting branches type I~II, small insertion angle; moderate to small leaves, short petioles, not prone to vegetative branches; strong boll setting, and good fiber quality. Such as 9665, JD~3, Fengmian No. 8, Jiumian No. 2, etc. 2. Deep Application of Base Fertilizer: The amount of chemical fertilizer is 8~12 kg of pure nitrogen, 7~10 kg of phosphorus pentoxide, and 3.5 kg of potassium oxide. When deep plowing to kill stubble, apply farmyard manure

A Complete Guide to Eggplant and Fruit Plastic Bag Preservation Methods
Place the selected eggplant fruits in a warehouse below room temperature of 20-25°C, stack them into piles, and seal them with a polyethylene film tent. The oxygen content inside the tent is 2%-5%, and the carbon dioxide content is 5%. Under these low-oxygen and high-carbon dioxide conditions, because respiration intensity is reduced and ethylene synthesis in the body is limited, and the action of ethylene is blocked, the detachment of eggplant stems is prevented and eggplant fruit rot is reduced. This method can store eggplant fruits for about 30 days, maintaining their original commercial value. Some people also use 10-micron-thick high-density polyethylene bags to store selected

How to release seedlings after mulching cotton fields with plastic film? Practical tips to share
In plastic-film-mulched cotton fields, the temperature is high, and seedlings emerge quickly and evenly. It takes 8 days from sowing to emergence, and 3 to 4 days after emergence for full stand. After full stand, if the late frost has passed, holes should be broken to release the seedlings. Releasing seedlings too early means they cannot achieve full stand or complete stand; too late is not good for strong seedlings, and if high temperatures occur, it often causes seedling scorching. For drill sowing, holes should be punched according to plant spacing to release seedlings; for hole sowing, holes should be punched according to seedlings. After breaking the film and releasing seedlings, cover the openings with soil to prevent moisture loss, temperature drop, film lifting by strong wind, and weed growth. When releasing seedlings, grasp the principle of releasing green but not yellow, that is, cotton seedlings with flat and expanded cotyledons can be released; yellow-valve seedlings that have not expanded, if released, are easily dried by wind or killed by sun, and cannot be released through holes.

Detailed Explanation of Key Techniques for Cotton Plastic Film Mulching Cultivation
Cotton plastic film mulching has the characteristics of stable yield, high yield, high quality and economic efficiency, with seed cotton yield per mu reaching over 100 jin. The main cultivation measures are: 1. Carefully prepare the land, choose plots with deep soil layers that retain fertilizer and water, make beds 60-70 cm wide and 8-10 cm high, and repeatedly press them twice with a wooden roller. 2. For seed treatment, sun the seeds, strictly select grains, delint with sulfuric acid, conduct germination tests, and soak the seeds in cold water before sowing. 3. Sow at the right time, with the best sowing period from April 25-30, maintaining 7500-850 plants per mu, and cover with film while sowing to avoid moisture loss.
