Water-saving and high-yielding rice, with a jasmine fragrance in every bowl
Wearing shoes to go into the paddy field, water-saving rice cultivation has become a reality. After the team led by researcher Luo Lijun at the Shanghai Agrobiological Gene Center created the world's first hybrid upland rice "Huhan 1A", it has achieved another breakthrough. Hanyou 3 has been approved, and under the condition of saving 50% of water resources, its actual yield per mu exceeded 500 kg for the first time. Shanghai's hybrid upland rice research took scientists 10 years, screened 10,000 resources, and selected more than 100 relatively drought-tolerant resources as parents for breeding. "The characteristic of hybrid rice is high yield, just like

Detailed Explanation of High-Yield and High-Quality Cultivation Techniques for Kernel Apricots
I. Orchard Site Selection. Kernel apricot trees can grow and bear fruit in areas with an altitude of 100-1800 m, a frost-free period of 100-220 days, an extreme minimum temperature below -34.7°C, an extreme maximum temperature above 43.3°C, and annual rainfall ≥35 mm (referring to conditions without irrigation). However, because apricot trees bloom early, planting is generally not suitable in areas where frost damage occurs frequently and severely during the flowering period. The orchard site should be selected in areas with no pollution of soil, air, or water. It requires a soil layer thickness of more than 50 cm, soil organic matter content

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

Several High-Yield Potato Cultivation Models Introduced
In recent years, the Potato Association of Ziyang District, Yiyang City has actively explored high-yield potato cultivation models and carried out contiguous demonstration planting in Xiangpulun Township, Yingfengqiao Town, Changchun Town and other places, forming a complete high-yield cultivation technology system. Spring potato - double-cropping rice cultivation. For spring potato, early-maturing varieties such as "Dongnong 303" are selected, sown from mid-to-late December to early January of the following year, and harvested from late April to early May. For early rice, late-maturing varieties are selected, using sparse sowing for strong seedlings or two-stage seedling raising, and after the potato harvest in early May,

What kind of soil standards do high-yield rice require?
(1) Distinct profile horizons, deep plough layer, good texture. For high-yield rice, a plough layer depth of about 20 cm is best. The plough layer should be fertile, thick and soft, with a high aggregate content, good structure and aeration, and suitable tillage properties. If the plough layer is too shallow, rice roots develop poorly; if too deep, floating mud forms easily, which is unfavourable for rice rooting and early growth. The texture should be moderate, neither too sandy nor too clayey: when dry-ploughed, the plough does not turn up large clods and the soil breaks up easily under harrowing; when wet-ploughed, it does not settle into a hard pan; when drained and dried, it does not crack widely, and the cracks close up easily after re-flooding.(2) Organic

Introduction to the high-yield rice variety Panjin No. 2
Panjin No. 2 (H148) is a super-high-yield new rice variety developed by our institute from a cross between line 27, which carries indica (IR36) bloodline, and Huangjin 300 grains in 1988, followed by multiple generations of selection. After it stabilized, it entered identification trials in 1992, entered the institute's variety comparison trial in 1993, and began external introduction and trial planting in 1995, fully demonstrating its characteristics of high yield, multiple resistance, and good quality. I. Characteristics and traits 1. Seedling stage: strong seed germination vigor, fast and uniform emergence, well-developed root system, sturdy seedlings, resistance to low temperature and tolerance to salinity and alkalinity

Detailed Explanation of a Reference Fertilization Model for High-Yield Rice
The soil-testing formula fertilization model for a rice yield of 450-550 kg per mu is as follows: (1) Total fertilizer amount and ratio The nitrogen, phosphorus and potassium ratio should be about 1:0.5:0.9, and the total amounts should be approximately: nitrogen 10-13 kg, phosphorus pentoxide 5-7 kg, potassium oxide 8-12 kg. (2) Fertilization plan 1. Basal fertilizer: (1) Organic fertilizer: generally for early rice, apply 1000-2000 kg of fresh green manure per mu, or 500-1000 kg of barnyard manure, or commercial organic

Demonstration and promotion of high-quality, high-yield rice for cold regions carried out in Heilongjiang
The National Agricultural Science and Technology Leap Program project "Integration and Demonstration of New High-Quality, High-Yield Rice Varieties for Cold Regions and Vegetative Matter Cultivation Technology" was officially launched on March 2 in Heilongjiang Province. The project is undertaken by the Heilongjiang Academy of Agricultural Sciences and Heilongjiang Bayi Agricultural University, and it is the first time that Heilongjiang Province's rice planting industry has been included in the National Leap Program. The project adopts three new high-quality, high-yield rice varieties of different maturity periods - Songjing No. 9, Longdao No. 5, and Longjing No. 14 - which were approved and promoted by the Heilongjiang Academy of Agricultural Sciences in the past two years and have passed national super rice acceptance, as well as vegetative matter pot seedling

New hybrid rice combinations achieve high yields in Hengxian
Recently, the new hybrid rice combinations "T You 551, Yue You 938, and Taixiang No. 5" introduced and trial-planted in Hengxian all achieved high yields upon expert inspection. The new hybrid rice combinations "T You 551, Yue You 938, and Taixiang No. 5" introduced in Hengxian were trial-planted on 140 mu across 3 villages and slopes in Nannan Township. Recently, the Hengxian Seed Company invited experts to conduct on-site inspection of the 3 new hybrid rice combinations. After experts randomly spot-checked 3 farming households on site, the inspection results showed: T You 551 rice had a wet grain yield of 650 kg per mu, and a dry grain yield per mu
