Sustained drought in Jiangsu, affecting the growth of wheat seedlings

Since September this year, precipitation in most parts of Jiangsu Province has been relatively small. Since October, most of the areas between Huaibei and Jianghuai in Jiangsu Province have experienced different degrees of meteorological drought, and the drought is still continuing. In the face of the new characteristics of meteorological drought in Jiangsu Province under the current drought and climate change, it is recommended to adopt scientific countermeasures to reduce the impact of meteorological drought on agricultural production.

In mid-September this year, precipitation in most parts of Huaibei, Jiangsu Province began to decrease. After October, the area with less precipitation increased, and the northeastern part of Jiangsu Province between Huaibei and Jianghuai experienced heavier meteorological drought. Since mid-November, the precipitation in the south of the Huaihe River in Jiangsu Province is only 0.2-10.0 mm. The rainfall in the Huaibei area has not fallen. The precipitation in the province has continued to decrease and the drought has further developed. Compared with the same period of the previous year, the northeastern region between Huaibei and Jianghuai is 7 to 90% less, and the other regions are generally 2 to 70% less. Xuzhou, Fengxian, Peixian, Qixian, Xinyi, Lianyungang, Handan, East China Sea The precipitation of cities (counties) such as Guanyun was the lowest since 1961.

Drought caused sorghum areas, some drought-stricken wheat fields lacked seedlings and ridges, secondary roots were underdeveloped, and the leaves at the base were yellow and so on. Serious fields even appeared dry and dead. Xuzhou Municipal Meteorological Bureau carried out soil moisture monitoring on unirrigated wheat fields on November 18, and some drought-ridden drought-ridden wheat fields have a dry soil thickness of about 8 cm. The severely affected area of â€‹â€‹the wheat field in the city is 2.5 million mu. The city's wheat area is 50%.

It is expected that the weather in Jiangsu Province will be fine on the 29th today, and there will be a weak precipitation process in the southern part of the province around the 30th. As the recent precipitation is still relatively small, the drought is expected to further develop.

Based on the current drought situation, it is recommended:

1. For the wheat fields in the dry areas with irrigation conditions, the water should be irrigated once to promote the seedlings and seedlings; for the high-lying mountain areas and dry farming areas without irrigation conditions, the water source should be actively digging and the watering area expanded.

2. Grasp the favorable weather and implement artificial rainfall enhancement.

Based on the new changes in the meteorological drought in Jiangsu, it is recommended that:

1 Strengthen the construction of farmland water conservancy facilities and improve the ability to resist drought and water supply.

2 Strengthen the capacity building of disaster prevention and mitigation such as departmental linkage and artificial precipitation enhancement, and promote the construction of meteorological services for agricultural services and meteorological disasters.

3 Strengthen agricultural adaptation to climate change scientific research, promote facility agriculture and stabilize production and increase production technology, timely plan and adjust crop variety layout and agricultural industrial structure, develop water-saving agriculture, and improve the ability of agriculture to adapt to climate change.

Hot Pipette Tips

The commonly used Pipette kits are mainly composed of a pipette and a pipette tip. The pipette tip is a single empty
Cavity reservoir; the pipette uses the principle of air displacement and controls the maximum displacement of the piston by rotating a screw with an ultra-fine thread
displacement, and then control the amount of liquid suction. There are the following problems when using the above kit for suction: 1. The suction volume is controlled by the pipette
After the pipette is sterilized or used for a period of time, it is easy to cause "hidden" failures, which cause the operator to be difficult to detect.
The actual suction volume is inaccurate, and it needs to be adjusted frequently, and the operation is cumbersome and time-consuming; 2. To improve the pipetting accuracy, the operator's
The operation requirements are high, and it is easily affected by factors such as the suction speed, the depth of the tip below the liquid level, and the inclination angle of the pipette.
The actual suction volume will be heard; 3. The actual suction volume will be affected because the suction head cover is not tight and leaking, and it will not be easily detected; 4.
When performing experiments that require high accuracy, such as analysis, in the operation of equal volume aspiration of liquids with different densities, the actual
The actual suction volume will be affected by the density itself; 5. In order to improve the accuracy, this type of pipette needs to carry out high
Cost-optimized design results in extremely high pipette costs.
