Cucumber Grafting


Cucumber grafting technology is the main measure used in cucumber planting to overcome continuous planting, improve plant resistance and yield. The grafted cucumber is good in against low temperature, high temperature, water logging and drought. After grafting, the cucumber seedlings will strong in growth and can even crop. 
   
Advantages of grafting: 
Improve the disease resistance capacity
For many years, cucumber are suffering from diseases such as Fusarium disease which do much harm to cucumber planting.
Yunnan black seed pumpkin are highly resistant to disease. After graftedwith Yunnan black seed pumpkin, it can be planted successively. If be grafted in right way, the disease-resistance rate will be as high as 100%.

Enhanced cucumber low temperature resistance capability
The black seed pumpkin can still grow in 8 Celsius which cucumber growth temperature can’t below 12 Celsius. So garden grafting clips with black seed pumpkin will help improve cold ability.

Increase cucumber production yield
Comparing to the cucumber seedling that is not grafted, the grafted cucumber harvest period prolongs(2 to 3 months longer).
Until now, the highest greenhouse cucumber yield is above 450,000 kg. However, those ungrafted cucumber yield is generally less than 75,000 kg per Ha.
Grafting preparation:

Rootstock choice:
Black and white seed pumpkin rootstock is common to see in cucumber planting. Black seed pumpkin rootstock is softer in low temperature and is widely applied in early-spring grafting. The white seed pumpkin rootstock is much softer in high temperature, so it is better to graft in summer or autumn. 

Grafting tools:
Blade,bamboo,garden grafting clips and sandpaper

New Irrigation Method

http://www.jlgreenhousesupplies.com/product/irrigation-pipe/irrigation-pipe.html
There are many water-saving irrigation methods such as Irrigation, micro-irrigation, sprinkler and drip irrigation. These methods are all controlled by people which are also called “passive irrigation model”. Israeli drip irrigation technology has been recognized as the best water-saving irrigation techniques.

Trace irrigation mainly refers to water-saving method which can long-term water corps in flow in ultrafine flow condition. It is said that the core water saving part is the irrigation faucet. It consists of high quality capillary bundles and irrigation film with filtration function. The water controller are buried beside the plant roots. The one end of the irrigation capillary bundles is connected to the irrigation hose supplier with full water. The other end link with the soil capillary in order to trace the water and soil change. When corps absorb water, the surrounding water level will decrease while stimulating water need signal. Faucets water will flow to the roots through capillary. The irrigation film inside the faucets can prevent faucet from being locked by impurities so as to keep long stable work. Drip irrigation and other water-saving irrigation methods have been widely used in agriculture. However, many farmers found that pipe blockage will be a big problem.Trace irrigation will offer new method to solve this problem.

Trace irrigation method refers to techniques that bury the trace irrigation hose supplier beside plant roots and transfer water and nutrition to the roots with a tiny water speed. This technique is now widely applied to greenhouse vegetables, fruit and tree planting. Trace irrigation hose can be buried 50 centimeter beneath earth to keep the integration of water and fertilizer.

It is said that since the trace irrigation hose supplier is buried under soil, it can save 50% water. Meanwhile, the faucet matched with film will help reduce irrigation blockage to achieve long last water supplies.

Experts said that, trace irrigation methods should be applied according to the actual situation.

Technology principle: since the irrigation pipe is buried, the water evaporation will be greatly reduced. With a minimum watering rate, plants can be obtained continuously water or nutrient solution to meet the growing needs. It will neither result irrigation water underground leakage nor produce water evaporation on the soil surface.

Key technology: the core part of trace irrigation is faucet which is made up by irrigation film and capillary bundles. The irrigation film has good effect on water filtration.
Economic Benefits: the water-saving effect is obvious for the irrigation hose can be reused for more than 5 to 10 years. With the development of technology, irrigation hose cost will also be reduced.

Shanghai J.L Horticultural and Agricultural Supplies is an irrigation hose supplier, the irrigation hose it offers enjoys high reputation around the world. If you are interested in irrigation hose, it must be a good choice.


 

    

How to Choose Flower Greenhouse Fans and Wet Curtain

Greenhouse fans and wet curtain now are widely used in flower planting and they do great effect on reducing temperature.

Working theory:
Let’s have a look at the working theory of greenhouse fans. First, greenhouse fan absorb the hot air outside and lower down the air temperature by the wet curtain. Generally, the wet curtain and the pumps and water tanks are installed at one side of the wall while greenhouse fans are centrally installed at the other side. The wet curtain should keep its moisture in order to make sure the completion of Evaporative cooling process. You can choose the suit greenhouse fans according the greenhouse size.

Evaporative cooling effect have tight connection with the air dryness, that is to say it closely related to the wet bulb temperature and dry bulb temperature of air. Furthermore, the wet bulb temperature and dry bulb temperature of air not only vary because of geographical and seasonal effects, but also change in a day. Although, the Wet and dry bulb temperature variations may be up to 14 ℃, but the magnitude of  wet bulb temperature change is only about 1/3 of the dry bulb temperature. Therefore, even in humid areas noon, evaporation system is still capable of cooling, which is also needed for greenhouse production.

Choose principle:
Usually in greenhouse flower production, the thickness of is often used in a fibrous wet curtain 10 cm thick or 15 cm thick of wet curtain should be better about 10 or 15 centimeter.
In addition to location and climate, you should also take greenhouse wet curtain and greenhouse fan distance and flower crops’ sensitivity to temperature into consideration. The father greenhouse wet curtain and fan distance is, the thicker wet curtain you should use(you’d better use 15 centimeter thickness).
