Detailed Explanation of Rice Paddy Soil Types and Nutrient Status in Sanming City
Our city has relatively abundant land resources, with a total land area of 34.44 million mu, of which cultivated land area is 2,563,100 mu, accounting for 7.4% of the total land area (of which paddy field area is 2,441,900 mu, accounting for 7.1% of the total land area, and agricultural land is 121,200 mu, accounting for 0.3% of the total land area). Due to differences in distribution terrain, paddy soils can be divided into four types: plain fields, sloping terraced fields, mountain valley fields, and streamside fields, with a ratio of 4.6:5:6.2:1 among them. Plain fields are dominated by hydromorphic

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

Detailed Explanation of Rice Field Cultivation Techniques for Agaricus bisporus (1)
Rice field cultivation of Agaricus bisporus is a planting method in which rice straw and other materials are used as the main raw materials, composted and fermented to make a growing substrate, and the temperature and light resources of autumn, winter and spring and the idle season are utilized to cultivate Agaricus bisporus in the open field in rice fields after the rice harvest. In 2005, our county used no-till cultivation in single-season rice fields in 12 townships (towns) to grow 300,000 sq m of Agaricus bisporus. As of April 15, 2006, the output value per sq m was 18.8 yuan. It is estimated that the output value per 667 sq m of mushroom field (actual cultivation area of 400 sq m) can reach 8

What are the cultivation methods for licorice? Detailed explanation of the key planting techniques
There are mainly two. (1) Direct seeding, generally done in rows, with a row spacing of 30-50 cm, a furrow depth of 3-4 cm, and 2 cm of covering soil, with a seeding rate of 2-3 kg per mu. Because direct-seeded products develop many branched roots, with the roots thick at the top and thin at the bottom, most fail to meet the quality standard, and because digging them out is laborious and highly labor-intensive, in production generally only seed-production fields use this method. (2) Seedling raising and transplanting, which is mostly used in production because of its high yield, excellent quality, low labor intensity, and high economic benefit. Generally, raising one mu of seedlings requires seeds

Detailed Explanation of Licorice Cultivation and Grassland Reseeding Techniques
Licorice (Glycyrrhiza) is a wild medicinal and forage plant. Based on its biological and ecological characteristics, adopting agricultural technical measures can break seed dormancy and increase the germination rate; meet the water and nutrient requirements of licorice growth and development, and increase its biomass yield. 1. Licorice cultivation techniques (1) Seed treatment. Use a rice mill to scratch the seed coat, taking care not to crush the seeds; milling twice gives the best results, and the germination rate can be increased from 30% to over 80%. (2) Site selection and pre-sowing land preparation. On sandy land, sand-covered land, and beach land types

Detailed Explanation of Key Techniques for Licorice Seed Treatment
Licorice seeds begin to germinate at 10-15°C, and germinate fastest at 15-20°C. The germination rate of old seeds decreases. One of the greatest characteristics of licorice is that it exhibits hard seediness, with the hard seed rate usually between 70-90%, making it very difficult for seedlings to emerge after sowing. Therefore, when propagating by seed in production, treatment before sowing is essential. The general treatment methods include the following: (1) soaking seeds in boiling water; (2) soaking seeds in concentrated sulfuric acid; (3) grinding with crushed glass; (4) milling with a rice mill. Among these, milling with a rice mill gives the best results. Generally, a few days before sowing, use a rice mill to mill the seeds 1-2 times.

How to Treat Licorice Seeds? A Detailed Guide to the Correct Method
The methods currently used in production are as follows: (1) Sand abrasion method: mix licorice seeds with clean river sand at a 1 to 1 ratio, put them into a container, and stir repeatedly so that they rub against each other; sow once the seed coat is no longer shiny. This method is labor-intensive and is only suitable for treating a small quantity of seeds. (2) Rice milling machine treatment: grind the licorice seeds with an electric rice milling machine for 2-3 passes, until the seed coat is scratched but the kernel is not broken. (3) Warming and repeated soaking method: soak the seeds in 60°C warm water for 6-8 hours, and use the "rice-washing method" to float off the seeds in the upper layer that have already absorbed water; then take the

Harm and Control Methods of the Licorice Seed Chalcid
Adults lay eggs on the seed coat of green fruits; after the larvae hatch, they immediately bore into and feed on the seeds, and pupate inside the seeds. After the adults emerge, they bite through the seed coat and escape. The infested seeds are eaten out into empty shells, and small round emergence holes are left on the seed coat and pods. This pest has a great impact on yield. Control methods: ① In winter, clear away residual leaves to reduce the source of the pest. ② Before sowing, the seeds must be treated, either by removing the insects or by dressing the seeds with carbaryl powder. ③ During the occurrence period, especially the green fruit stage, spray with pesticide.
