What are the key points of the double-cropping peach cultivation technique?
With advances in breeding technology, extremely early-maturing peaches (such as Siyuehong peach and Wuyuecui peach) and extremely late-maturing peaches (such as Xue tao, Sheng tao and Dong tao) have appeared one after another, creating favorable conditions for extending the market supply period of peach fruit and improving the economic benefits of peach growers. However, in actual cultivation, early-maturing peaches shed leaves early, have many flower buds and a high fruit yield, and are prone to early tree decline. Late-maturing and extremely late-maturing peaches consume few nutrients in the early growth stage, and the trees are rich in nutrients and grow too vigorously, leading to relatively serious fruit drop, which brings difficulties to growers' cultivation management. If extremely early-maturing peach varieties are top-grafted into the inner canopy of late-maturing and extremely late-maturing peach trees,

Detailed Explanation of Key Points of Potato Double-Mulch Cultivation Technology
Potato double-mulch cultivation technology is a comprehensive cultivation technique combining plastic film mulching with arched sheds, mainly addressing frost damage to early-spring potatoes in northern regions, promoting early sowing and early marketing of potatoes, and increasing farmers' income. Potato double-mulch cultivation generally brings potatoes to market 30 days earlier than plastic-film potatoes, with a per-mu yield of up to 2500 kg and a per-mu income of over 2000 yuan, showing very significant economic benefits. Its main cultivation techniques are: 1. Site selection and shed construction. For double-mulch cultivation, a long strip of land 50-60 m east-west and 6 m north-south should be selected.

Detailed Explanation of the Double-Ridge, High-Moisture, High-Yield Cultivation Technique for Potatoes
The main feature of the double-ridge, high-moisture potato cultivation method is the optimized integration of good seed, good methods and a good growing environment. Its core technique is the "six changes": first, changing from the use of multiple, inferior and mixed varieties to the use of leading improved varieties; second, changing from intercropping corn with potatoes to growing potatoes alone; third, changing from the "starry sky" planting method to double-ridge, high-moisture cultivation; fourth, changing from one intertillage and ridging to two or three intertillages and hillings; fifth, changing from one-sided application of nitrogen fertilizer to balanced fertilization based on soil testing and formula (mainly phosphorus and potassium fertilizers); sixth, changing from rough field management to fine management (with the focus on timely irrigation

Detailed Explanation of the Double-Row High-Yield Potato Cultivation Technique with Ridging
The double-row high-yield potato cultivation technique with ridging is a comprehensive high-yield potato cultivation technique based mainly on deep loosening, ridging with deep fertilizer application, and rational close planting in double rows. It generally increases yield by more than 15% compared with conventional flat-bed cultivation, and raises the marketable rate of qualified tubers by more than 20%. Main technical points: 1. Select suitable varieties. At present, the main varieties promoted for planting in the south are Sishu No. 1, Atlantic, Jinkou 303, Holland No. 7, Holland No. 15, Dongnong 303, Kexin No. 4 and other early-to-mid maturing, high-yield, high-quality potato varieties. 2. Strictly select the site and prepare the soil finely. Select

Double mushroom showcase: two mushroom varieties each display their strengths
The Horticulture Research Institute of the Provincial Academy of Agricultural Sciences used single-spore hybridization, single-spore systematic selection and molecular marker-assisted selection techniques to breed the low-temperature-tolerant, high-quality, high-yield new brown button mushroom (Agaricus bisporus) variety "Zongxiu No. 1" and the new white button mushroom variety "Yingxiu No. 1", which have passed the first national batch of edible fungi variety certification. The new brown button mushroom variety "Zongxiu No. 1" has a cap surface of natural brown, with white stipe and flesh. The mushroom quality is excellent, the fruiting bodies are round and neat, the caps are thick and firm, and not sunken at the top; the flavor is delicious and the texture is tender. Because its cap is naturally brown, it requires no

Chinese-American biologist successfully breeds double-gene transfer cloned pig
The University of Connecticut in the United States announced recently that renowned Chinese-American biologist Yang Xiangzhong, in cooperation with the scientific research department of Taiwan, China, has bred the world's first double-gene transfer cloned pig carrying human coagulation factor IX and porcine lactoferrin. This research achievement is expected to be used to treat hemophilia. According to Yang Xiangzhong, a professor at the University of Connecticut, this research was conducted under extreme secrecy by his research team in cooperation with the Taiwan Animal Technology Research Institute. The first cloned pig was born on February 15 this year at the Taiwan Animal Research Institute

Detailed Explanation of the Double-Ridge High-Mound High-Yield Cultivation Technique for Potatoes
Potatoes grown with the double-ridge high-mound cultivation method are deeply favored by the vast number of farmers because they are free of disease, show a large yield increase, have good tuber shape, and a high marketable rate. As a result, double-ridge high-mound cultivation has become a technical measure commonly adopted by farmers in Xuanwei. The characteristics of the "double-ridge high-mound" potato cultivation method are the optimized integration of good varieties, good methods, and a good growing environment; the goal is to increase potato yield and the marketable rate and raise farmers' incomes; the core of the technique is the "six changes," namely: first, change from using multiple, inferior, and mixed varieties to applying leading improved varieties; second, change from intercropping corn with potatoes to growing potatoes alone;

New Technique for Whole-Seed Potato Cultivation with Plastic Mulch and Double Rows on High Ridges
1. Reasonable crop rotation and stubble reversal To economically and effectively utilize soil fertility and prevent soil-borne diseases, pests, and weeds, avoid continuous potato cropping or planting potatoes on the stubble of other root and tuber crops. Also, do not rotate with other Solanaceous crops such as eggplant and tomato, otherwise yields will be reduced by 15%-20%. Potatoes can be rotated with cereal crops and legume crops for more than 3 years. 2. Land preparation and ridge formation Potatoes are suitable for planting in deep, loose soil, with deep plowing and fine land preparation. After harvesting the previous crop, promptly clear the stubble, plow deeply about 25 cm

High-Yield Spring Cultivation Techniques for Potatoes in Double-Cropping Regions
I. Select High-Quality Virus-Free Seed Potatoes In double-cropping regions, the spring period suitable for potato growth is relatively short (60-70 days), so it is essential to select early-maturing virus-free varieties with a short dormancy period, early tuber formation, rapid tuber expansion, strong stress resistance, and high quality and yield, such as Yupotato No. 1 and No. 2, and Favorita. The seeding rate is 120 kg per mu. II. Early Cutting and Early Sprouting 1. Warm the seed potatoes and cut them. Before cutting, place the seed potatoes in a room or a sun-heated cold frame at 12-15°C for 5-7 days to warm them, prompting the seed potatoes to break dormancy and the eyes to sprout. About 2
