Key Points of High-Ridge Double-Row Potato Cultivation Technology
High-ridge double-row potato cultivation refers to a planting method using wide and narrow rows, where soil from the wide rows is hilled onto the narrow rows, forming raised beds that stand more than 25cm above the ground. Trials have confirmed that potatoes grown on ridges and beds have the advantages of earlier emergence, a higher proportion of large and medium tubers, and higher yields; ridge-bed cultivation increases yield by 19.1% compared with flat-bed cultivation. The specific cultivation techniques are as follows: 1. Fine seedbed preparation. Potato is a shallow-rooted crop. After the tubers are planted and before emergence, the better the root system develops in the soil, the stronger the plant growth after the seedlings emerge.

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

Four Effects on Rice After Exposure to High Temperatures
Rice has different temperature requirements at each growth and development stage, and there is an optimal temperature for each. If the upper or lower critical temperature limit is exceeded, abnormal phenomena, namely physiological disorders, will appear in the growth and development of rice. Therefore, attention should be paid to the effects of high temperatures on rice. 1. Effects of high temperatures on each growth stage of rice. 1. Heading and flowering stage. Generally, rice prefers a temperature of 25-30°C during the heading and flowering stage. When the temperature is below 25°C or above 30°C, large numbers of empty and shriveled grains will appear in rice. At the same time, high temperatures also

How to prevent rice sheath blight? Beware of high temperature and high humidity weather
Sheath blight, also known as banded leaf blight, has a great impact on the growth and development of rice. It not only weakens the absorption capacity of the root system, but also affects the photosynthesis of leaves, resulting in an increase in empty and shriveled grains, a decrease in 1000-grain weight and a decline in yield. Therefore, attention should be paid to the prevention and control of sheath blight in production. The following introduces the main symptoms, occurrence characteristics and control methods of this disease for reference. Main symptoms When rice leaf sheaths are infected, small dark green water-soaked spots with blurred edges appear near the water surface, later expanding into oval or cloud-like shapes, with the center grayish green

Impact of High-Temperature Heat Damage on Rice Production in Fanchang County and Defensive and Remedial Measures
In the process of rice production, the climate factors with the greatest impact and the hardest to control are temperature and water. Reasonable irrigation can supplement and regulate water, but temperature is difficult to control, and it exerts a major influence on the entire life of rice. Rice is the main crop in grain production in Fanchang County, ranking first among grain crops in both planting area and total output. At present, the rice planting area in Fanchang County is about 16,360 hectares (including the multiple cropping index), of which about 13,191 hectares are middle-season indica rice (mainly hybrid rice), about 1,514 hectares are early rice, and about 1,655 hectares are double-cropping late rice.
