How to grow licorice for high yield? A full breakdown of the technical key points
1. Soil selection. Choose deep soil layers, good drainage, high-lying terrain, and sandy soil and sandy loam soil with relatively high calcium content. Waste flats and waste slopes with slightly alkaline soil and a pH between 7 and 8.5 can all be cultivated. Plots with low-lying terrain and heavy clay soil must not be planted. 2. Variety selection. Choose the new "Wosheng licorice" variety suitable for artificial cultivation. This variety has the following characteristics: First, strong adaptability, drought resistance, cold resistance, salt-alkali resistance, heat tolerance, and tolerance to poor soil. Its temperature adaptation range is 43 to 45°C. In areas with severe water shortage or relatively dry conditions, no wilting or death has been found, and it can adapt to weakly alkaline calcareous soil. At the same time, it is suitable for intercropping with young forest and fruit trees; second, a short growth cycle. With seedling raising and transplanting, the seedlings grow for 3 to 4 months, and after planting they can be harvested after 8 to 10 months of growth; third, fast growth. Because of its prostrate growth habit, combined with artificial cultivation techniques, it grows horizontally at 30 cm on the soil surface, and its absorption rate of natural conditions such as light, water, and fertilizer is high, so its growth speed is fast. Thirty days after sowing, 3 to 4 true leaves appear. At 60 days, the plant height is 30 cm, the root length can reach 20 cm, and the diameter is 0.5 cm; fourth, harvesting and processing are simple. All operations can be mechanized, less labor is used, and it can be sold after being naturally dried to 80 percent; fifth, high yield and good quality. The yield of medium rough grass per mu is more than 500 kg, and high-yielding fields can reach 800 kg. The skin is red, there are few branches, and the strips are uniform. It meets the standards of the national pharmacopoeia and complies with the germplasm requirements for building a GAP production base.

How to prevent and control jujube fruit shrink disease? A full analysis of the key technical points
Jujube fruit shrink disease is a new disease of jujube trees, often occurring together with anthracnose. When this disease breaks out severely, it causes reduced yields in mild cases and total crop failure in severe cases, and in recent years it has caused huge losses in the jujube-growing areas of our city. The disease mainly damages jujube fruit, causing fruit rot and fruit drop. It occurs during the coloring stage of jujube fruit; in our city it begins in mid-to-late July, and mid-to-late August is the peak period of the disease. Affected jujube fruit first shows a pale yellow halo on the fruit shoulder and body, which then gradually expands into round or irregular water-soaked discolored lesions, with a round brown spot in the center; the flesh in the diseased area

How to control oleander aphids? A full breakdown of practical methods
Oleander aphid, also known as the kapok aphid, belongs to the order Homoptera, family Aphididae. It is distributed throughout southern China, as well as in various countries of Southeast Asia, Africa, and South America. Damage symptoms: nymphs or aphids attack oleander, stunting the growth of affected new shoots, turning the upper and lower leaves black, and causing flower buds and flowers to develop incompletely and open abnormally, reducing ornamental value. Morphological characteristics: the wingless parthenogenetic female is oval in shape, 2.3 mm long, yellow like a banana peel. The frontal tubercles are raised, higher than the median frontal tubercle; the antennae are dark, with coarse tile-like sculpturing; the rostrum reaches the middle coxae. The cornicles are long and tubular, dark

How to make a banyan bonsai? A full breakdown of the detailed method and steps
The banyan tree is an evergreen tree species of the genus Ficus in the mulberry family. It likes light and prefers a warm, humid, rainy climate. It is not cold-tolerant and slightly shade-tolerant, and is suited to growing in fertile, loose, moist alluvial soil. The branches of the banyan tree produce aerial roots that can hang down to the ground, giving it a very good ornamental effect. Its crown is relatively spreading and it has strong sprouting ability, making it a good bonsai tree species. I. Seedling sources Banyan stock is mainly selected from seed-grown seedlings and cutting-grown seedlings. Sowing is generally carried out in February to March each year, and the small seedlings can be divided and transplanted after 1 year. Cuttings are usually taken in February to March each year, and are divided and transplanted after 1 year.

How to care for water-and-land bonsai? A full analysis of practical tips
Watering: Water-and-land bonsai are planted in very shallow pots, so special attention must be paid to replenishing water in time. To prevent the potting soil from being washed away when watering, it is best to use a fine-nozzle watering can. When the climate is dry, a sprayer can be used to mist the pot surface, the trees and the rocks to keep the moss growing well. Fertilizing: The soil in water-and-land bonsai is relatively little and nutrients are limited, so attention should be paid to fertilizing to keep the trees growing vigorously. Fertilizing is mostly done by spraying diluted organic fertilizer water onto the soil surface. Granular organic compound fertilizer can also be buried in the potting soil. Repotting: The trees in water-and-land bonsai are generally repotted once every 3 to 5 years, mostly

Rabbits Have Particular Water Needs: A Full Breakdown of Scientific Watering Methods
As the saying goes, "Better to lack a handful of grass than a mouthful of water," which fully illustrates the importance of drinking water for rabbits. So, what exactly does water do for a rabbit's growth, what happens after a rabbit is short of water, and how do you give rabbits water scientifically? 1. The role of water in rabbit growth. In the various tissues of a rabbit's body, water accounts for 70%, and in the blood it can reach 80%; the water content of bones, muscles and internal organs is 45%-75%. Not only is water indispensable for the digestion, transport and absorption of nutrients from all kinds of feed, the excretion of waste products and toxins produced by metabolism is also inseparable from water.

How Does the San Jose Scale Spread? A Full Analysis of Control Measures
I. Distribution and Damage The San Jose scale (Quadraspidiotus perniciosus) in the Korla region mainly damages pear, apple, apricot, peach, hawthorn, grape, and white poplar, among other fruit trees and forest trees. The insects cluster densely on the branches and trunk in the upper canopy and inner part of the crown, with more on smooth-barked areas and the sunny side. Population density is highest on 2- to 5-year-old branch sections, and on 1-year-old branches they mainly gather around the bud bases. The San Jose scale sucks the sap of branches, leaves, and fruit as female adults and nymphs. Young branches and leaves dry up and fall off after being damaged; damaged fruit develops purplish-red
