How is rice dry-raised? Keep these thirteen points in mind
The trayless seedling-throwing technique for dry-raised rice uses a rice-specific slow-release medicinal-fertilizer super-absorbent seed coating agent called "Dry-Raising Nanny" to coat rice seeds, carry out dry seedling raising, and after pulling the seedlings, directly throw them into the field. It is a light, simplified, and cost-saving rice cultivation technique. Its key cultivation points are as follows: 1. Select the correct model. For application in dry-raised seedling throwing, the seedling-throwing type of "Dry-Raising Nanny" should be chosen. 2. Determine the dosage. Each bag (350 grams) of "Dry-Raising Nanny" super-absorbent seed coating agent coats 1-1.5 kg of rice seed. 3.

Rice gene design breeding: scientists cultivate new varieties
The aroma of rice is richer, like fruit, with higher iron and zinc content, so there is no need to supplement other nutrients; all of this can be achieved through molecular design of rice genes. Recently, the author learned from the "Crop Molecular Design and Innovation" symposium that China is currently building a large bioinformatics infrastructure platform to ensure that high-quality genes are "hit every time." Zhu Yingguo, an academician of the Chinese Academy of Engineering, said that taking rice as an example, japonica rice with a soft and glutinous texture is more favored, and people also hope that rice aroma will be richer or have special aromas such as "fruity" notes. Moreover,

Detailed Explanation of Key Licorice Cultivation and Management Techniques
Licorice, also known as sweet grass root, red licorice, and powder grass, is a leguminous plant, with its root and rhizome used as medicine. Licorice is a perennial herbaceous plant, 30-40 cm tall. The root is thick and sturdy, cylindrical, with a sweet taste, and the outer bark is brownish-red. The stem is upright, slightly woody at the lower part. The leaves are alternate, and the flowers are papilionaceous, light purplish-red. The seeds are flat and round. The flowering period is June-July, and the fruiting period is July-September. Licorice is sweet in flavor and neutral in nature, with effects of clearing heat and detoxifying, moistening the lungs and stopping cough, and harmonizing various medicines, and is regarded as the elder of all medicines. Except for waterlogged lowlands and land with a high groundwater table, which are not suitable for planting, other

How to Choose and Prepare the Site for Licorice Cultivation? Detailed Technical Points
Licorice has a very strong rhizome sprouting ability, extending horizontally beneath the soil surface around the old plant; one licorice plant can produce dozens of new plants within a few years. Under artificial cultivation, 3 years after sowing, new plants can be seen growing 3-4 meters away from the mother plant. Its vertical rhizome can also develop roots. The depth of the root system varies with soil texture and the depth of the groundwater table, generally within the range of 1-2 meters, sometimes reaching more than 10 meters, using the deep root system to absorb groundwater and adapt to arid environmental conditions.
