Detailed Explanation of Key Points for Plastic Mulch Potato Cultivation Techniques
I. Sowing time. Sow early at the right time. In plain areas, sowing is generally done from late January to early February. In mountainous areas, sow after the ground thaws, generally from mid-to-late March to early April. II. Sowing method. For direct ridging, sow while there is still moisture after ridging. If the soil is dry before sowing and the underlying moisture is insufficient, first irrigate in spring to build up moisture; do not sow when moisture is lacking. Plant two rows per ridge, planting in the middle of the ridge. It is strictly forbidden to plant at the edge of the ridge or even on the ridge slope. When sowing, distribute the seeds evenly in a triangular arrangement. For furrow-and-ridge planting, complete ridging, sowing, and film covering in one operation, and be careful not to sow too deep, to prevent

Plastic Film Mulch Cultivation Techniques for Potatoes in Winter Fallow Fields
When cultivating potatoes in winter fallow fields, if the plastic film mulch cultivation method is adopted, the potatoes can be brought to market earlier, thereby achieving higher economic returns. The key cultivation techniques are as follows: 1. Soil selection - Choose slightly acidic light sandy soil that is loose, well-aerated and well-drained for cultivation. Clayey soil is heavy, poorly aerated and drains badly, which is unfavorable for tuber development and unsuitable for growing potatoes. When using harvested late rice paddies to grow spring potatoes, be sure to choose raised fields and second-bank fields with loose soil and good drainage. Potato

Detailed Explanation of Key Techniques for High-Yield Cultivation of Garlic with Plastic Mulch
The yield-increasing effect of plastic mulch on garlic is very obvious. Compared with open-field cultivation, garlic under plastic mulch has significantly better roots, stems and leaves than open-field garlic; the yield of garlic scapes is 35% higher than open-field cultivation, and the yield of dry garlic bulbs is 30% higher than open-field cultivation. Its main cultivation techniques are: 1. Sowing at the right time. The optimal period for sowing garlic is to let the plants grow to 5-6 leaves before overwintering; at this time the plants have the strongest cold resistance, will not be killed by freezing in the severe winter, and lay a good foundation for the plants to successfully pass vernalization. The suitable sowing period for plastic-mulch garlic, from the Beijing area to the Handan area, is roughly between the two solar terms "Autumn Equinox" and "Cold Dew," that is, from the end of September to the beginning of October.

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,

What are the key management points for garlic under plastic mulch during the green-up stage?
1. Clean the plastic mulch surface to increase its light transmittance. The key to garlic green-up is temperature, and management during this period focuses mainly on raising soil temperature. For garlic covered with plastic mulch, coverings on the film such as leaves, completely dead garlic leaves and dust should be removed as early as possible to clean the film surface, so as to increase light transmittance and raise soil temperature. Damaged plastic mulch should be repaired promptly to increase heat preservation and warming effects and promote early green-up of garlic. 2. Open and clear ditches. Garlic roots are not tolerant of wet conditions; waterlogging in the field during spring rain can easily cause root rot, and drought can also affect normal garlic growth.

Six key points to master for garlic cultivation with plastic mulch
Garlic cultivation with plastic film mulch has a significant yield-increasing effect and very obvious economic benefits. During cultivation, attention should be paid to the following six aspects: Fine land preparation and fertilization: prepare the land carefully and increase the application of organic fertilizer, applying 5000-7500 kg of decomposed organic fertilizer per mu. For plastic film mulching, small raised beds are generally used, with a bed width of 70 cm and a bed spacing of 20 cm. Plant 4 rows per bed, with a row spacing of 15 cm and a plant spacing of 10 cm. For mulching with plastic film, generally sow first and then cover with film. The film should be covered tightly and pressed down firmly so that it fits closely against the ground with no gaps and no wrinkles. Any holes should be promptly plugged with soil.

Summary of Experimental Trials on Delayed Cultivation Techniques for Hongxue Peach in Plastic Greenhouses
Hongxue peach is an extremely late-maturing peach variety. When cultivated in the open field in our county, the fruit is difficult to ripen due to late-autumn rainfall and frost. Therefore, starting in 2001, we conducted delayed cultivation trials in plastic greenhouses using technical measures such as early promotion followed by later control, delayed flowering, bagging to protect against rain, and covering the greenhouse to regulate temperature, prevent frost, and protect leaves. The results showed that facility-grown Hongxue peach bore fruit in the second year after planting, entered full production in the third year, could delay fruit ripening by about 20 days, and markedly improved fruit maturity and the rate of high-quality fruit.

Detailed Explanation of Key Techniques for Cultivating Gastrodia elata in Plastic Bags
Plastic bag cultivation of Gastrodia elata is generally carried out in October-November. 1. Method of planting Gastrodia in plastic bags with fungus sticks inside: Make polyethylene plastic bags 45-50 cm long and 28 cm wide. Disinfect the inside of the plastic bag with a 0.2% potassium permanganate aqueous solution, place a small amount of basic culture material and small wood blocks (preferably humus soil) at the bottom layer, then stand 2 high-quality fungus sticks with a diameter of 5-6 cm and a length of 20 cm upright inside (if the fungus stick diameter is greater than 7 cm, 1 stick can also be placed). While filling the bag with humus soil,

Key Points of Late-Stage Management and Plastic Mulch Coverage Techniques for Lilies
I. Late-Stage Management (1) Timely removal of bulbils. Bulbils should be harvested on a sunny day, and care must be taken to avoid breaking the plants or knocking off the upper green leaves. (2) Shading and cooling, clearing ditches to reduce humidity. Shading is a measure to prevent high temperatures. Adding a straw cover at the seedling stage can reduce water evaporation and lower soil temperature for the late-stage growth of lilies. (3) Increasing fertilizer application. After the bulbils are harvested, the leaf color of lilies gradually becomes lighter, indicating that nutrients have become imbalanced, and nutrients must be added to prevent premature senescence of the lilies. At this time, an appropriate amount of quick-acting chemical fertilizer should be applied as a supplement. During the flowering period of lilies, applying 2

Plastic-mulched cotton grows vigorously, so lodging and premature senescence must be prevented early
Many cotton farmers, in the process of growing plastic-mulched cotton, are prone to some technical mistakes that cause cotton plant lodging and premature senescence. The former is triggered by removing the film too late, while the latter is caused by untimely or insufficient topdressing. Therefore, the following measures should be taken promptly: remove the plastic film at the right time. Plastic-mulched cotton has a much stronger capacity to absorb fertilizer and water in the early stage than directly sown cotton. If the film is removed at the right time and field management is strengthened, plastic-mulched cotton can give full play to its advantages; if the film is removed late or not removed at all, it is not conducive to the cotton roots growing downward, causing most roots to be distributed in the upper soil layer,
