Major progress made in project to control soybean yield reduction from continuous and alternating cropping
The reporter learned from relevant departments that the project "Research and Demonstration of Key Technologies for Controlling Soybean Yield Reduction under Continuous and Alternating Cropping," tendered by the Municipal Science and Technology Bureau, has achieved major progress after two years of scientific research. The project was carried out in Yilan and Bayan counties, the two counties with the largest soybean area in Harbin. Through key technology research, soybean varieties resistant to continuous and alternating cropping were selected, including Kenfeng 16, Heinong 48, Kangxian 4, and Hefeng 47. A formula fertilization technique was proposed with 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium, and

How to Grow High-Yield Soybeans? A Detailed Guide to the "Four Changes and One Addition" Cultivation Technique
Traditional drill sowing of soybeans results in narrow rows and overcrowding, and along with various other factors, yields have long hovered around 100-150 kg. Through years of experimental research, we have developed a new approach that can increase soybean yields by more than 40%, namely the "Four Changes and One Addition" technique. The usual measures for increasing soybean yields include, besides selecting new high-quality, high-yield varieties, paying attention to crop rotation. According to experiments, after years of continuous cropping, soybeans show slow growth, short plants, yellowing lower leaves, early leaf drop, and few pods with small seeds. Experiments

Detailed Explanation of High-Yield Soybean Cultivation Techniques in the Northern High-Cold Region
The scope covered by this model includes the vast areas of the northern part of the third accumulated temperature zone and the fourth accumulated temperature zone in Nehe, Keshan, Yi'an, Kedong in northern Qiqihar, Heilongjiang, and Wudalianchi, Nenjiang, Bei'an, Xunke, Aihui, Sunwu and other counties (cities and districts) of Heihe City. The soybean planting area in this region is about 10 million mu, which has a decisive influence on soybean production in the entire province and even the whole country. This region has a large cultivated land area, a high degree of mechanization, and a commodity rate as high as 70%. It is an important soybean export base for the province and the country.

Early-maturing soybean Chaofeng No. 3: an excellent variety with super-high yield, high resistance and high efficiency
Chaofeng No. 3 soybean is an early-maturing variety with super-high yield, multiple resistance and high efficiency, bred over 8 years by researchers at the Research Institute of Jilin Province Northern Seed Industry Company. This variety overcomes the prominent problems of the past, when large-scale production applications were not high-yielding, had poor internal quality, failed to meet national quality standards, and were prone to pod shattering in dry years, resulting in high but unstable yields and high yields without high returns. In March 2007, it successfully passed provincial certification. Chaofeng No. 3 has a growth period of 110 days, and from sowing to harvest requires an active accumulated temperature of 2300°C

How to prevent low yields in Gastrodia elata? Master these measures
1. Poor quality Armillaria mushroom-wood material. Most farmers habitually use old wood logs from previous years' Gastrodia elata planting as mushroom-wood material, that is, the old-log-plus-new-log method of cultivating Gastrodia elata. Old wood logs have poor wood quality; not only have most of the nutrients already been consumed and used up, and the Armillaria aging phenomenon is serious, but there are also many factors carrying miscellaneous molds, which not only harms the growth of Gastrodia elata but also destroys the environmental conditions for Armillaria growth, so that the Armillaria source cannot well supply nutrition to Gastrodia elata, resulting in low per-unit yield of Gastrodia elata, or even total crop failure. 2. Use of multi-generation seed with degraded varietal characteristics

Key High-Yield Techniques for Cultivating Oyster Mushrooms on Rice Straw
High-Yield Techniques for Cultivating Oyster Mushrooms on Rice Straw 1. Selecting spawn: Experiments show that the relatively ideal strains include: the low-temperature type 792 and 118 oyster mushrooms; the medium-temperature type Xinnong No. 1, 9400 oyster mushroom, and Hypsizygus marmoreus; the high-temperature type Hainan No. 2, etc. (All of these spawns can be provided by the Binhai County Edible Fungi Research Institute.) 2. Seasonal scheduling: Along the middle and lower reaches of the Yangtze River, sowing can be done from early August to mid-February of the following year, with mid-September to mid-November being the best sowing period. 3. Rice straw selection: Choose fully dried, mold-free, golden-colored rice straw

Detailed Explanation of High-Yield Cultivation Techniques for Spring-Planted Potatoes
Potatoes have the characteristics of being nutrient-rich, serving as both food and vegetable, high-yield and efficient, and having a short growth period. In recent years, with the adjustment of agricultural structure, the potato planting area has increased year by year. The main high-yield cultivation techniques are: selecting improved varieties. Our province belongs to the spring-autumn double-cropping potato region, so early-maturing varieties should be selected that tuberize early, have fast tuber expansion, a short dormancy period, high yield, good quality, and disease resistance, such as Yu Potato No. 1, Yu Potato No. 2, etc. These varieties are best as virus-free seed potatoes. Virus-free potato seedlings emerge early, have robust plants, large leaves, and a

Key Points of High-Yield Spring Potato Cultivation Techniques
Potato is a dual-purpose grain and vegetable crop. Its tubers are extremely resistant to storage and transportation, making it a major vegetable for balancing market supply during peak and off-seasons. Dianzi Township in Pingyin County has accumulated rich experience in potato cultivation and achieved significant economic benefits. Land preparation and fertilization: In early March, once the soil has thawed, begin land preparation immediately. At the same time, through deep plowing and fine harrowing, apply 2000-3000 kg of high-quality farmyard manure and 50 kg of superphosphate per 667 sq m (1 mu), then mix evenly and level the soil. Seed potato treatment: Select high-quality, high-yield, early-maturing virus-free Luyin No. 1 for the potato crop. 5 to

Four Key Points for High-Yield Cultivation of Spring Potatoes
Last October, many people in this village sowed potatoes, but a frost hit and they were all frozen to death. I sowed potatoes twice myself, at the end of January and in February this year; although they were not frozen to death, they only grew foliage and produced few and small tubers, and many had their centers hollowed out by termites. In addition, he used continuous cropping. The reader asks when it is more suitable to sow potatoes, and how to prevent frost damage and termites. For spring potatoes to be high-yielding, the main attention should be paid to the following four aspects: Pay attention to timely sowing. If spring potatoes are sown too early, the seedlings are prone to frost damage and death after emergence.
