Improved Cuttage Propagation of "Geranium"
In cuttage propagation of geraniums, because their stems are semi-succulent and contain a lot of water, rot often occurs and affects survival. For this reason, over the past few years the author has made certain improvements in combination with heavy pruning after flowering, so that when cuttings are taken at that time, the survival rate can be markedly increased. The specific method is as follows: select thick, strong branches on the plant, and from the top tip downward, at intervals of every 4 to 6 true leaves, or cut sections 7 to 10 cm long, until reaching the height of the usual heavy pruning of the plant after flowering, and plan in advance to divide them into several cuttings. Then, at a distance of

The dace is an aquatic improved species with relatively high economic value for farming.
Dace is also known as river fish and slippery fish. There are more than 20 species of dace worldwide, distributed only in China, Japan, Korea and the eastern part of the former Soviet Union. China has about 10 species of dace, mainly distributed in the waters of northern China. The species vary by region; those with mature farming technology and relatively high economic value include: 1. Baikal dace. Mainly distributed in the **Burqin area of China. This fish is a small to medium-sized precious fish, weighing 100-200 grams, with excellent flesh flavor, strong reproductive capacity and high population yield. 2. Northeast dace. Most are distributed

Supporting Technologies of Improved Soybean Varieties and Methods for High-Yield Cultivation
1. Timely sowing: Select varieties with high yield-increase potential adapted to the local area, and sow at the right time. Apply herbicide before sowing soybeans, and apply herbicide again after sowing depending on the weed situation. Sowing time: spring soybeans from late April to early May, sowing depth 5 cm; soil moisture conditions must be given great attention at sowing. The conditions for soybean seed germination mainly include moisture, temperature and oxygen. ① Moisture: seed germination begins with water absorption, so water is an important factor for germination. When seeds germinate, the water absorbed equals 1.21

Rice cultivation in cold regions requires water-saving irrigation, selection of improved varieties, making the most of accumulated temperature, and growing strong seedlings
Heilongjiang Province is located in a high-cold region, where heat and water resources are relatively scarce, annual atmospheric precipitation is extremely unevenly distributed, spring is windy with little rain, and drought is quite severe. The author discusses how to achieve water-saving, high-quality, and high-yield rice cultivation in cold regions. 1. Selecting excellent varieties is the prerequisite for ensuring high-quality and high-yield rice. The varieties that rice farmers plant directly affect the quality and yield of rice. Therefore, in production, varieties with a suitable maturity period, excellent quality, stable and high yield, and strong stress resistance should be selected. First, select varieties that have passed national approval, been named, and promoted, which can ensure relatively stable rice traits, steady and rising yields, and safe and reliable use; second, introduce varieties with suitable maturity periods according to different accumulated temperature zones, and never introduce varieties across zones; third, pay attention to seed quality, and select first-grade improved seeds with a purity above 98%, a germination rate above 90%, and a moisture content no higher than 14% for production use; fourth, purchase seeds from nationally certified seed companies, research institutes, and agricultural colleges, and eliminate blind planting; fifth, in actual planting, unify varieties as much as possible, plant in contiguous fields, form scale, and achieve industrialized planting.

Long-finned koi successfully bred at aquatic improved variety trial farm
In Renhe Village, Bingcun, Meixian, there is a farmer named Qiu Dong. Two years ago, he suffered a natural disaster while growing golden pomelo, and nearly 400,000 yuan of investment was almost completely lost. He then switched to raising grass carp, but an 8-mu pond earned him only about two thousand yuan in a year, unable to make ends meet, and he fell into no small amount of debt, with his finances in dire straits. One day, a fisheries expert appeared and showed him a kind of fry, which brought a turning point in his life. Now, he has become a locally somewhat well-known "fish" farming specialist, with an annual net income of more than 20,000 yuan, and has led three or four neighboring relatively poor villagers to prosper together.

How can the water color of eel culture ponds be improved?
During the culture process, the pond water color changes unpredictably, indicating that phytoplankton have died in large numbers, zooplankton such as rotifers and water fleas have increased sharply, dissolved oxygen and pH have decreased, harmful gases have increased, eels have reduced feeding, and floating head has appeared, leading to disease and death. The improvement methods are as follows: 1. Light green turns transparent: This phenomenon is caused by massive reproduction of zooplankton such as rotifers and water fleas. Trichlorfon at 0.5 ppm plus potassium permanganate at 2 ppm can be used to kill excess rotifers and water fleas, or a large water exchange can be used; stock 500 g or more per fish of bighead carp per mu

Gui Green No. 1: Introduction to a national-level improved tea tree variety with Guangxi's independent intellectual property rights
Tea is an important economic crop in China, and in particular one of the pillar industries for poverty alleviation and prosperity in the mountainous areas of Guangxi. With the rise of organic tea (green food) production, some varieties with resistance to pests and diseases and strong adaptability have received attention. Varieties determine characteristics such as the sprouting period of tea trees, processing suitability, quality traits and resistance. To develop tea production, tea products must be early to market, distinctive, of superior quality and favorable in price to be in a position to seize the market. Therefore, to make Guangxi's tea industry strong and large, we must start from the "source" - adopting superior
