New high-yield techniques for lotus root: straw-fed lotus cultivation and lotus-fish polyculture
In April 2006, the Yindu Industry, Trade, Science and Technology Ecological Park in Wenshang County, Shandong Province, was completed and put into operation. Using waterlogged, saline-alkali and barren land, through scientific methods and the implementation of multi-component composite three-dimensional development, a science and technology ecological park was built integrating vegetable and forage cultivation - livestock and poultry breeding - straw-fed lotus cultivation - fish farming in lotus ponds - fishing and leisure - dining and entertainment, and other functions into a circular economy development model, achieving remarkable economic and ecological benefits. In particular, the new corn straw-fed lotus cultivation technique promoted by the park can achieve a lotus root yield of up to 6000 kg per mu.

Grass chickens are in high demand in the market, and skillful raising can achieve high profits
Grass chickens (also known as local native chickens) have wide adaptability, strong foraging ability, tolerate extensive management, and are easy to raise. Their skin is thin and bones are fine, and the meat is delicious, tender, fragrant and tasty; they are a natural green food and are deeply favored by consumers. Judging from the current market conditions, the market price of live grass chickens is generally more than 1 times that of broiler chickens, and the price per kilogram of eggs is about 5 yuan higher than that of eggs from introduced breeds. Therefore, grass chickens have become a major farming project actively developed by many farmers. However, in order to make grass chickens gain weight quickly and reach market earlier, some farmers feed only a single type of concentrate

New High-Yield Cultivation Technique for Soybeans: "Four Changes and One Addition"
With the traditional tillage and sowing method for growing soybeans, the rows are narrow and the plants too dense, and combined with various other reasons, yields have long hovered around 100-150 kg. Through years of experimental research, we have worked out a new approach that can increase soybean yields by more than 40%, namely the "Four Changes and One Addition" technique. The usual measures for raising soybean yields, besides selecting new high-quality, high-yield varieties, also include paying attention to crop rotation. According to experiments, after many years of continuous cropping, soybeans show slow growth, short plants, yellowing lower leaves, early leaf drop, and few pods with small seeds. Experiments have also proven that continuous cropping (monocropping) for more than 3 years can reduce yields by 20%-30%, or even more, and 2 years of continuous cropping following a one-year break can reduce yields by more than 30%. Therefore, crop rotation and changing to a different crop are of great significance in soybean production. To achieve high-yield and super-high-yield soybean cultivation, the new "Four Changes and One Addition" cultivation technique should be implemented on this basis. The specific methods of "Four Changes and One Addition" are:

Zhonghuang 13, the new high-yield soybean variety with the largest promotion area
The new high-yield soybean variety "Zhonghuang 13", supported by the national "Institute Directors Fund" (basic research operating expenses for public welfare research institutes), has now become the soybean variety with the largest promotion area in China, reaching a record 10.87 million mu in 2007. Zhonghuang 13 (National Approved Soybean 2001009) was bred under the leadership of the famous Chinese soybean breeder, Researcher Wang Lianzheng of the Chinese Academy of Agricultural Sciences, and was recommended by the Ministry of Agriculture as a national key soybean variety for three consecutive years from 2005 to 2007. It was developed by sexual hybridization using Yudou 8 as the female parent and Zhongzuo

Detailed Explanation of Key Points for High-Yield Cultivation Techniques of Angelica sinensis
Angelica sinensis, also known as Qin Gui, Minshan Gui, Xi Danggui, and Yun Gui, contains various volatile oils, with main components including n-butylidene phthalide, ligustilide, carvacrol, angelica aromatic ketone, palmitic acid, sesquiterpene A, B, etc. The root is used as medicine, and it has the effects of regulating menstruation and relieving pain, moistening dryness and lubricating the intestines, and breaking blood stasis to promote regeneration. It is a commonly used gynecological remedy in traditional Chinese medicine. With the continuous development of China's traditional Chinese medicine industry and the worldwide "traditional Chinese medicine fever," the demand for Chinese medicinal materials is increasing day by day. As a bulk commonly used Chinese medicinal material, Angelica sinensis has an extremely broad market prospect and is a new path for farmers in the high-altitude mountainous areas of Yunnan Province to escape poverty and become prosperous.

Angelica sinensis with shade net coverage: high yield increase and quality improvement benefits
The shade cultivation technique for Angelica sinensis starts from the three-leaf stage of its growth (that is, from mid-May to early August after summer begins, when temperatures are high and light is intense). A shade net with a 50% shading rate is timely placed over Angelica sinensis, providing a suitable micro-environment of moderate temperature, weak light, and moisture that mimics its original ecological growing conditions. By lowering temperature, increasing humidity, and reducing light, it reduces the early bolting rate of Angelica sinensis in dry flatland cultivation to about 30%; moreover, shade cultivation of Angelica sinensis also helps prevent and reduce pest and disease damage, thus improving the quality of Angelica sinensis.

Key Technical Points for High-Yield and High-Efficiency Off-Season Cultivation of Oyster Mushrooms
Oyster mushrooms can be cultivated all year round, but those cultivated in the high-temperature season yield the highest returns. The reasons: First, high summer temperatures make cultivation technically difficult, and pests and diseases occur easily, often leading to cultivation failure. Second, the total cultivation area of oyster mushrooms in summer decreases, and total output is small, causing a shortage of fresh oyster mushrooms@#@125@#@ on the market and driving prices up. Based on years of cultivation practice at our edible fungi research center, as long as the key technical points are grasped and some necessary scientific management methods are adopted, oyster mushroom cultivation can still achieve high yield and high efficiency. The key cultivation and management technical points are introduced below:

Key Points of Off-Season Cultivation Techniques for Oyster Mushrooms During High-Temperature Periods
Off-season cultivated edible mushroom products often sell for 4 to 6 times the price of those in the regular season, yielding quite remarkable returns. To improve off-season edible mushroom cultivation during high temperatures, our institute has explored off-season high-temperature cultivation techniques for oyster mushrooms over the past few years. The results show that off-season oyster mushroom cultivation not only has a high success rate, a short time, fast fruiting and easy management, generally fruiting in 15 to 20 d, with a biological conversion rate of over 90%, but also has a short cycle and significant benefits. It is introduced as follows: 1 Cultivation time arrangement Conventional oyster mushroom cultivation generally stops going to market in mid-May each year.

Detailed Explanation of Key Technical Points for High-Yield Cultivation and Management of Agaricus bisporus
I. Cultivation Season In the Weibei Dry Belt region, where temperature differences are large, air humidity is low, and seasons change quickly, sowing can be done earlier, scheduled from mid-August to early September. In the Guanzhong Plain area, it is scheduled from late August to mid-September. Of course, mushroom growers with cave dwellings or fruit cellars can pile and ferment right after the wheat straw harvest, sow by the end of July, and harvest by late August. After the corn stalks are harvested, once the corn stalks are dry, a second round of sowing can be carried out, using cut corn stalks + cow dung, sowing from December to January, overwintering, and starting to produce mushrooms in March of spring
