How does the domestic geranium reproduce?
The most practical way to raise flowers in family is to use cuttings in pots. Cuttage time 4-5 months or 8-9 months is appropriate, should be determined according to the local temperature (18-20℃) growth season specific cutting time; culture soil to loose ventilation drainage, the best choice of sand, pearlite, rotting soil each a mixture, or coarse river sand, ripe soil or expanded pearlite, are required by the sun exposure and other methods of disinfection after application. Cuttings can be combined with spring and autumn pruning, choose a year without pests and diseases to develop healthy young shoots for cuttings, about 8 cm long, in the

Causes of Soybean Flower Drop and Its Control Techniques
There are many reasons for soybean flower drop and pod drop, mainly: poor ventilation and light transmission soybean is easy to cause flower drop and pod drop under poor ventilation and light transmission conditions. Soybean planting due to improper varieties, premature ridge closure, but also due to excessive density, branches and leaves shield each other, coupled with high humidity, poor light, low chlorophyll content of leaves, so that soybean plants gradually yellow. Nutrient accumulation is little, cause flower pod to fall off. The flower and pod dropping stage of nutrient imbalance soybean is the period of highest nutrient demand. If the nutrient supply is insufficient, the flower and pod will fall off. Fertilizer requirements for soybeans

Control of two main diseases of soybean
Soybean gray spot, also known as spot disease, pods began to occur from the tender pod stage, grain filling stage is the peak period of the disease, from July to August with high temperature and heavy rain. It mainly harms the leaves. When the disease is serious, almost all the leaves are covered with disease spots, causing the leaves to fall off prematurely, the soybean quality is reduced, and the yield is reduced by 20% to 30%. This year, the high-temperature and rainy climatic conditions in many places in our province are very conducive to the occurrence of the disease. The author reminds soybean farmers not to ignore the prevention and control of soybean gray spot. Chemical control: use more than 50% bacteria per mu during the flowering and pod stage of soybean.

Cultivation method of soybean with two ridges and one furrow
The cultivation method of two ridges and one furrow is on the basis of 70cm ridge cultivation, adding a row of seedling belts in every other ridge, 140cm with large row spacing, 35cm with small row spacing, sparse outside inside the furrow and platform, and hole sowing cultivation. The reasons for increasing yield were as follows: (1) the green area was increased and the canopy structure was improved. (2) the condition of ventilation and light delivery is improved. (3) the ability of drought resistance has been improved. (4) the heat resources are fully utilized and the ground temperature is increased. (5) the supply of soil nutrients was improved.

Matching techniques for high yield of improved varieties and methods of soybean
1. Sowing at the right time, select the varieties with high potential to increase production in this area, and sow at the right time. Use herbicides before sowing, and then use herbicides according to grass conditions after sowing. Sowing time, spring soybeans from the end of April to the beginning of May, sowing depth of 5 cm, sowing must pay great attention to soil moisture. The main conditions for soybean seed germination are water, temperature and oxygen. ① moisture: seed germination is first of all water absorption, so water is an important factor in germination. The amount of water absorbed by seeds during germination is equivalent to 1.21 of the seed weight.

Key points of fresh-keeping technology of mushroom
The main factors affecting the preservation of mushrooms are as follows: temperature: the higher the temperature, the worse the preservation of mushrooms. 0-4 ℃ is the suitable temperature for mushroom preservation. In addition to quick freezing, freezing injury is easy to be caused when the temperature is less than 0 ℃. Water quality: when the content of iron or copper in the water is more than 2 mg / L, the mushroom color darkens and turns brown, so iron and copper utensils and tools are prohibited. Humidity: 95-100% required. Less than 90% of the color darkens and it is easy to open an umbrella and deteriorate. Gas composition: it contains important causes of decay, which can be inhibited by sterilization and adjusting pH value. Enzyme activity

Prevention and control of "three insects and one disease" of mushroom
The "three insects and one disease" harmful to autumn mushrooms are mites, jumpers, mushroom mosquitoes and harmful verrucosporium. The characteristics and control methods of these diseases and insect pests are described as follows. 1. In the process of the occurrence of symptoms caused by mites, if the hyphae are found to have the phenomenon of returning bacteria, such as the decrease of villous hyphae, the increase of simple hyphae, and the pink bright spots on the surface of the hyphae, the mite head appears in the mushroom bed. When there are 3 to 5 mites in the range seen with a magnifying glass, the control target is reached. After covering the soil, the mites will move with the soil surface as the hyphae grow to the soil surface, and concentrate.

Prevention and treatment of mushroom "freak"
Deformed mushrooms are prone to deformed mushrooms when the ventilation is poor and the carbon dioxide content in the mushroom exceeds 0.3%. The mushroom part is too deep, and the mushrooms that grow between the cracks in the coarse soil are often deformed. Preventive measures, we should focus on the ventilation of mushroom rooms. Pleurotus ostreatus culture material into the mushroom room humidity is too high, coarse soil water transfer mushroom room ventilation is too long, covering fine soil too late, low temperature, easy to produce Pleurotus ostreatus. Preventive measures should be mastered to spray appropriate amount of water, timely ventilation, so that the mycelium hanging above the clay, under the fine soil.
