How to grow potatoes with hotbed seedling raising and transplanting for high-yield cultivation?
Using the "plastic hotbed seedling raising and transplanting potato high-yield cultivation measures", the yield per plant generally reaches 1.8 kg, with a maximum of 3 kg, and the yield per mu can reach 5000-7000 kg. The specific measures are as follows: 1. Careful selection and treatment of seed potatoes. Select large potatoes with regular shape, free of pests and diseases, and free of frost damage as seed. The seed potatoes are taken out of the cellar on March 10-13, placed on the normal-temperature ground of a greenhouse for 6-9 days in spring, and cut into seed pieces when white dots appear at the buds. Each potato piece weighs about 30 g, and generally 36-40 pieces are cut per kg of seed potatoes.

Detailed Explanation of Super-High-Yield Cultivation Techniques for Shengtai No. 1 Rice
Shengtai No. 1 is a super-high-yield, disease-resistant new variety bred by the Rice Research Institute of the Guangdong Academy of Agricultural Sciences. It passed crop variety approval in Guangdong Province and Shaanxi Province, and received the first-ever subsidy from the Ministry of Agriculture of the People's Republic of China for high-quality and special-purpose new varieties of major crops. When cultivated in Jieyang City, its full growth period is about 132 days for the early crop and about 122 days for the late crop, belonging to the medium-late maturity type suitable for both early and late seasons. Its stem and leaf morphology is coordinated and rational, with a well-developed deep root system, medium-strong tillering ability, good fertilizer tolerance and lodging resistance, suitable for planting in areas with medium or higher fertility, with obvious yield-increasing effects. The panicles are large and long, with dense grain setting, and the panicle-grain structure

Xindou No.1, a high-quality, high-yield soybean variety
Xindou No.1 was developed by Huanong Hualin (Beijing) International Agricultural Development Research Center based on the basic principles of soybean breeding in China, using conventional hybridization and modern advanced breeding methods. Xindou No.1 was bred with Brazilian Ziyou soybean as the female parent and Lufeng soybean as the male parent, through ten years of selection, with 1-4 generations of backcrossing, and selected from the progeny. This variety adapts to the climatic conditions of most regions in China, and can be planted on mountain ridges, hilly ridges, sandy land, low-lying alkaline land, and poor land. It can be planted on a large scale in China except in a few local areas.

How to Achieve High Yield and High Efficiency in Soybeans? Six Measures to Help You Get There
Matching superior varieties with good methods. While planting existing high-yield, high-quality soybean varieties in the project area, new and superior varieties such as Jidou No. 12, Handou No. 3, Jihuang No. 13, and Japanese high-oil soybean were introduced according to local conditions through a combination of introduction, demonstration, and promotion, bringing the coverage rate of superior varieties in the soybean project area to 100% and laying the foundation for matching superior varieties with good methods. Seed dressing with molybdenum fertilizer to increase the pod-setting rate. In high-yield soybean areas, use 3 grams of ammonium molybdate per mu, dilute with water into a 2% solution, and dress 1 kg of soybean seed. According to multi-site trials, soybeans treated with molybdenum

Key Points of High-Yield Cultivation Techniques for Direct-Seeded Soybean after Wheat Harvest
The Longkou City Agricultural Technology Promotion Center conducted a two-year study on summer direct-seeded soybean after wheat harvest. The experiment used the Ludou 11 variety, and the yield per 667 sq m reached more than 300 kg. Through the experiment, the wheat-soybean direct seeding method replaced the wheat-corn relay intercropping model, with a significant increase in benefits, raising income by more than 400 yuan per 667 sq m. The key techniques are early seeding by rushing the stubble, single-seed sowing, density control, and timely harvest. 1. Variety selection and treatment. Select varieties with stiff stems that do not lodge

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

How can high yield be achieved in delayed autumn cultivation of potatoes?
Delayed autumn cultivation of potatoes means that potatoes planted in the open field are covered with a shed and plastic film before the arrival of early frost, so that they are protected from early frost damage, make full use of late autumn light conditions, extend the potato growth period, increase yield, improve market quality, and achieve high yield and high efficiency. 1. Site selection: Choose plots with loose, slightly acidic soil, rich in organic matter, deep plow layer, and easy drainage and irrigation. The previous crop is best to be millet, wheat, or corn; for vegetables, the previous crop is best to be scallions, garlic, celery, or carrots. Remember that continuous cropping must not be practiced, and the previous crop must not be a plot of Solanaceae crops, in order to reduce potato diseases and

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

How to Achieve Early Maturity and High Yield in Soybeans
1. Choose suitable varieties. When selecting seeds, choose varieties with shorter plant height that can be planted at wider spacing; these varieties have relatively lower water requirements and suffer less yield loss in dry years. 2. Strengthen field management and weed promptly. Weeds compete with soybeans for fertilizer and water, affect photosynthesis and hinder ventilation, so weeds must be removed promptly. Cultivate and hill up at the right time. When cultivating and hilling, cultivate deeply and hill up plenty of soil to enhance soil permeability and its capacity to retain water and fertilizer. 3. Apply sufficient base fertilizer. On the basis of applying farmyard manure, the amount of chemical fertilizer applied must not be

Interplanting autumn soybeans in rice paddies yields good increases in both output and income
According to trials: after the mid-season rice harvest, by using the temperature and light conditions in the field, planting an additional season of autumn soybeans can increase soybean yield by 60-120 kg/mu, with economic income of 150-420 yuan/mu, giving a relatively good effect of increasing both output and income, and it is suitable for extension in ratoon rice areas below 400 m in altitude. The key technical points are as follows: 1. Suitable site and good varieties: fields below 400 m in altitude with no water for retaining ratoon rice, as well as all rice seed production fields, can be planted. After the rice grains have set, open ditches to drain water; after the rice harvest, promptly clear weeds and rice stubble, without plowing, and according to
