How to grow spring-planted soybeans in Northeast China? A detailed explanation of the technical guidance
In the autumn and winter of last year, precipitation in Northeast China was lower than normal, soil moisture was insufficient, and drought was relatively severe. This spring there has been more rain and snow, temperatures began to rise rapidly in early April, and temperature and precipitation are close to normal. The Soybean Expert Steering Group of the Ministry of Agriculture, together with the National Agricultural Technology Extension Service Center, based on full investigation, proposed the following technical guidance for spring soybean planting: 1. Strictly select excellent varieties. Because of the dry climate last autumn, soybeans may not have matured normally physiologically at harvest, and mechanical threshing increased the possibility of damage to the seed embryo

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

What are the cultivation and management techniques for spring-planted potatoes?
Spring Planting Cultivation Techniques for Potatoes. Potatoes have the characteristics of high yield, early maturity, multiple uses, and wide distribution. In recent years, the spring planting area in our region has expanded year by year. 1. Land preparation. Potatoes prefer sandy loam and loam. Deep plowing and winter irrigation can be carried out before winter, with 2500-3000 kg of organic fertilizer applied per mu, and the land leveled before sowing with sufficient bottom moisture irrigation. Through the shallow plowing and fertilizing method, 25 kg of potassium sulfate, 25 kg of diammonium phosphate, and 15 kg of urea per mu are broadcast on the surface and incorporated into the soil with a rotary tiller. When ridging, the ridge

Detailed Explanation of Key Spring Potato Management Techniques
Breaking the Film to Expose Seedlings A After potato seedlings emerge and turn green, promptly break the film to expose the seedlings to prevent high temperatures from scorching the young plants. When cutting the film, do not injure the seedlings, and the opening in the film should not be large, generally 3-5 cm. Cutting the film is best done in the morning. After exposing the seedlings, promptly seal the openings to help retain heat. Early Fertilization After potato seedlings emerge, if there is drought, apply 1000-1500 kg of high-quality manure to achieve both drought resistance and nutrient supplementation. If soil moisture is good, apply 10-15 kg of urea in holes. When seedlings grow to 50 cm, apply 15 kg of urea per mu in holes.

How to Plant Spring Potatoes? Planting Methods and Key Technical Points
There are three methods for early-maturing spring potato cultivation: double-film covering with plastic film plus small arched shed, thick-film small arched shed covering, and flat plastic film mulching. Potatoes cultivated using these methods can be brought to market 10 to 20 days earlier than potatoes grown with conventional open-field cultivation. Selecting good varieties: Regardless of which covering method is used, the original seed of Dongnong 303 or Kexin No. 4 introduced from Northeast China must be used. Self-saved seed must not be used, and local seed that has been self-saved for many years, with aging varieties and seriously degraded seed characteristics, must certainly not be used. About 150 kg of seed is needed per mu. Large potatoes can be cut open for planting, with each seed

Master the Three Earlies and Three Skills for Spring Potato Planting to Achieve High Returns
Three Earlies: Choose early-maturing varieties. Practice has proven that selecting high-yielding, high-quality, virus-free potato varieties with a growth period within 70 days (from emergence to harvest) is the key to achieving high, stable yields and quality in spring-planted potatoes. Currently ideal varieties include Holland No. 7, Holland No. 15, Zhengshu No. 6, etc. Start sprouting early. Using a sunny cold frame before planting to pre-sprout can make potatoes emerge early and uniformly, with complete and strong seedlings, promoting early plant development and early tuber formation - this is an important yield-increasing measure. The key points of sprouting technique are: before planting

Key Techniques for Three-Membrane Covered Cultivation of Winter-Spring Potatoes
Three-membrane covered cultivation techniques for winter-spring potatoes (large arch shed, small arch shed, plastic film). Generally, sprouting is promoted and sowing is done in December, and harvest takes place at the end of March the following year. Each mu can yield about 3500-4000 kg of potatoes. It reaches the market one month earlier than early-spring plastic film covered potatoes, and the economic benefits are very significant. The cultivation techniques are as follows: 1. Site selection, shed construction specifications and planting specifications (1) Site selection and shed construction specifications. Choose plots with loose soil, sufficient water sources, and convenient drainage and irrigation to build sheds. Large arch sheds are generally 60 m long

How to grow spring-planted garlic for high yields? Master these four cultivation points
Garlic planted in spring and harvested in summer has a shorter seedling stage and less nutrient accumulation, so both yield and quality are inferior to autumn-planted garlic. To improve the yield and quality of spring-planted garlic, you must select good varieties and focus on management. The key is to do well in the following four aspects: 1. Choose suitable varieties: spring-planted garlic takes about 100 days from planting to harvest, and the whole growth period is very short, so choose short-growing-period purple-skin garlic as seed garlic. 2. Apply heavy base fertilizer: before sowing, while preparing the land, apply 3000 kg of high-quality human and livestock manure or barnyard manure per mu, 15:

Key Points for Simple Spring Cultivation Techniques of 'Zhengsong No. 1' Scallion
I. Variety Introduction 'Zhengsong No. 1' has tall plants, thick and long white stalks, rapid growth, high yield, strong stress resistance, and a delicious flavor. It can be sown in both spring and autumn. II. Land Preparation and Sowing Sow from March to May in spring using the furrow direct sowing method. Apply sufficient base fertilizer: 3-5 cubic meters of farmyard manure and 40-50 kg of ammonium bicarbonate per mu. After plowing, directly lay out lines and open furrows with a furrow spacing of 70 cm, furrow width of 20 cm, and depth of 20 cm, with two rows per furrow. Before sowing, first broadcast compound fertilizer in the furrow, then hoe once to make the soil and fertilizer uniform. Along both sides of the furrow, open two small furrows in parallel, and in the small

Key Technical Points for Over-summering Management of Spring Bag-cultivated Shiitake Mushrooms
After the color change of spring bag-cultivated shiitake mushrooms is completed in mid-June, the high-temperature season begins. Shiitake mycelium is intolerant of high temperatures and drought; when the temperature exceeds 35°C and persists for 4 hours, the mycelium begins to die, or even self-lyse. The following are the key technical points for ensuring that mushroom bags safely over-summer in production, for the reference of mushroom growers: 1. Cooling. Use shade, ventilation, sprinkling water on the ground, hanging clean wet burlap pieces and other methods to lower the temperature, so that the substrate temperature does not exceed 30°C. On sunny summer days, close doors and windows from 9 o'clock until sunset to prevent hot air from entering the room. 2. Shading. Thicken the shading
