Detailed Explanation of Key Points of Potato Intercropping and Relay Cropping Techniques
Intercropping and relay cropping of potatoes with grain, cotton and vegetable crops can greatly improve the utilization of light energy and land, and increase the economic benefit per unit area. Test results from Zhangqiu City, Shandong Province show that cotton-potato relay cropping can yield more than 260 kg of lint cotton and more than 2,100 kg of potatoes per mu; spring potato - corn - autumn potato intercropping and relay cropping can yield 2,100 kg of spring potatoes, 590 kg of corn and 1,300 kg of autumn potatoes per mu. The net benefit of these two cultivation models can be 100 percent higher than that of monoculture cotton or corn.

How effective is the Jiaduo frequency-vibration insect-killing lamp at trapping and killing the rice stem borer?
The rice stem borer is one of the important pests in rice production in Wuchang City. In recent years, with changes in rice varieties and warming climate conditions in our city, the occurrence and damage of the rice stem borer have become increasingly serious. According to this autumn's survey, for certain varieties in Wuchang, the average number of insects per 100 steps per mu reached more than 20,000, with the highest in key outbreak areas reaching 60,000, and in some cases more than 100,000. Such insect numbers are rare in history, whether domestically or abroad. In order to further control the damage of the rice stem borer, explore new approaches to its control, and reduce pesticide pollution of rice. This year our city set up at Sun Guanghao's field in Lianhua Village, Wuchang Town

How to prevent fish from gasping at the surface? A detailed guide to practical and effective measures
Discharge an appropriate amount of pond water and add fresh water; the suitable time for adding water is around 2-3 p.m. Use aerators reasonably, stop fertilizing, and control fish feeding. Splash quicklime water in small amounts several times to adjust the pH of the water body. Use chlorine dioxide twice in succession to disinfect the water body; before disinfection, an appropriate amount of oxygen enhancer and microecological preparations may be applied.

Pingxiangli Pear
It is a new cultivar bred by the Fruit Tree Research Institute of the Jilin Academy of Agricultural Sciences. The parents are Pingguoli (Apple Pear) × Yanbian Xiehuatian, crossed in 1956. It has been promoted in Jilin, northern Liaoning, Inner Mongolia, and the Bashang area of Hebei, and has been introduced and trial-planted on a certain scale in **, Guizhou, Jiangsu, Gansu and other provinces (autonomous regions). The fruit is medium to large, with an average single-fruit weight of 120 g and the largest reaching 216 g. The fruit is nearly round or oblate, the skin is greenish-yellow and turns yellow after being stored for some time, some have red dotted blush, and the appearance is relatively attractive. The fruit surface is smooth

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

Common field planting patterns for intercropping cotton with potatoes
The cotton-potato intercropping pattern is widely used in northern Jiangsu; the two crops have a short symbiotic period, little mutual influence during that period, and a complementary effect in fertilizer use. The ample fertilizer and water in the field during the late growth stage of potatoes favor cotton seedling development, allowing a double high yield of both cotton and potatoes. Generally, potatoes yield 2000-2500 kg per mu and cotton yields 80-100 kg per mu, with an output value of 2500-3000 yuan per mu and a net income of 1500-2000 yuan. The bed is generally about 3 m wide, and cotton is planted in wide and narrow rows, with wide rows 150 cm apart and narrow rows

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

What preparatory work is needed for shaping lingzhi bonsai
1. Choose good shaping varieties. In addition to collecting wild lingzhi with odd shapes from nature, a large amount of raw material comes from cultivation. At present, the main varieties available for selection include red lingzhi, purple lingzhi, black lingzhi, pine-fir lingzhi, pine-fir tree lingzhi, tropical lingzhi, Neo-Japanese lingzhi, and more than ten other kinds that can be selected for matching. 2. Make shaping primordia. Bonsai lingzhi can be cultivated in bottles or bags (if conditions do not permit, production can be entrusted to a nearby cultivation site). Generally, bag cultivation has sufficient substrate and produces large fruiting bodies; bottle cultivation has limited substrate and tends to produce a single lingzhi.

Practical Techniques and Experience Sharing on Lingzhi (Reishi) Bonsai Shaping
1. The caliber of the cultivation container controls the density of the fungal branches. If a large-capacity, wide-mouth bottle of 1000 ml to 3000 ml is chosen, the fungal branches will mostly form clusters of lingzhi (reishi), resembling swirling colorful clouds; if an infusion bottle is used for cultivation, it will mostly produce single branches with long stems, and a single-stemmed lingzhi symbolizes the ruyi scepter; if a canning jar is used for cultivation, two lingzhi can be kept and tied together to form mandarin-duck lingzhi, the best gift for newlyweds. 2. Oxygen-controlled shaping. Place lingzhi that has already formed a cap but has not stopped growing into a poorly ventilated container (such as a vat or bucket) to promote the appearance of a proliferated layer beneath the cap.
