Forecast of grassland insects trend in Ordos City in 2005
For a long time, due to serious over-grazing, grassland and other human factors caused by grassland degradation and temperature rise, the Ordos grassland has become a frequent and re-emergence area for grassland pests, with an average of 20 million mu per year. The grassland is invaded and destroyed by various grassland pests and rodents, and the area of ​​serious damage is more than 10 million mu.
I. Main occurrence and control of grassland pests in 2004
As of August 6, 2004, the area of ​​grassland pests in Ordos City was 10.13 million mu, of which the serious area was 4.785 million mu. The pest species are mainly aphids, spring worms and grasshoppers. The locusts in Erdos City have an area of ​​4.9 million mu of grassland, with a serious area of ​​2.18 million mu, mainly occurring in Eqi, Hangjinqi, Wushenqi and Zhunqi. Grassland crickets occur in a large area of ​​grassland and marginal farmland in Erdos City, with an area of ​​2.93 million mu, mainly occurring in Eqianqi, Wushenqi and Yiqi, with a serious area of ​​1.47 million mu. Spring stalks mainly occurred in Hangjinqi and Eqi, with 2.3 million mu, and a serious occurrence of 1.135 million mu. Grassland pests cause the young leaves and flower buds of the grassland to be damaged, the growth is hindered, and the insects are very serious. By the end of September, the city had completed a total of 25.93 million mu of grassland pest control, with an average efficiency of over 90%. Among them, there are 510,000 mu of spring stalks, 961,000 mu of locusts, and 1.12 million mu of grassland.
Second, the forecast of grassland insects in 2005
According to the monitoring of some pest species in the autumn of 2004 combined with the occurrence of grassland pests in Ordos City in recent years and the eradication of the disease in 2004, it is estimated that the area of ​​grassland pest pests in Ordos City will still be around 9 million mu in 2005, of which serious harm The area is at least 5 million mu. specifically:
It is estimated that from the middle of April to the beginning of June, about 1.5 million mu will occur in the Hangjinqi, Eqi, Dongsheng and Wushenqi shrub grasslands, and the serious area is expected to be about 1 million mu;
The grassland is known as the god worm. When it encounters the right climatic factors, it will suddenly erupt. In 2002, there were 11 million mu of land in Ordos. In the winter and spring, the Ordos city has more precipitation. Therefore, at least 3.5 million is expected in 2005. The acres are in the Yiqi, Zhunqi, Daqi, Eqi and other places of artemisia and annual natural grassland, the serious occurrence area is about 2 million mu;
The locusts accounted for only about 1/20 of the area under the control area in 2004. If the rain is sufficient and the temperature is suitable, it is expected that the locusts will have a large area of ​​nearly 3 million mu in Eqi, Hangjinqi, Qianqi and Wushenqi in 2005. Occurred, the serious area is expected to be more than 2 million mu;
In addition, the locusts are expected to occur in nearly 700,000 mu on the sheep and firewood fields in Hangjinqi and Eqi, etc.; the gray-spotted moths are expected to occur in the holly and overlord pastures of Hangjinqi, about 500,000 mu; the bitter bean moth is expected to be in front. The flag is about 300,000 mu of bitter bean grass. The chafer and white thorn are also partially on the 100,000 mu artificial grassland and white thorn grass field.
3. Prevention and control of grassland pests and diseases in 2005
According to the above trend forecast, we must do a good job in the early preparations for the spring report and the elimination of the disease, and try our best to reduce the damage caused by the pests to the grassland.
First of all, in March, we will do a good job in forecasting and forecasting all kinds of grassland pests, and provide reliable first-hand information for accurate and rapid implementation of the disease.
Secondly, according to the situation of measurement and reporting, we will do a good job in the prevention and control of grassland pests according to local conditions, and report to the higher-level business and competent departments in a timely manner, and at the same time actively carry out the work of eliminating the connection of drugs and eliminating funds for the treatment. Specifically:
In 2005, the area of ​​grassland pest control in Ordos City should be at least 5.5 million mu, with a total cost of RMB 6.05 per mu. While actively pursuing the allocation of drugs from higher-level business departments, we must also promptly contact the local government at the two levels of the city to partially eliminate the funds for ground support (including fuel costs, machinery hire purchase fees and ground staff subsidies, etc.). Calculated at 0.4 yuan per mu, a total of 2.2 million yuan is subsidized by the local government. In addition, in view of the more serious grassland rodent pests in Ordos City in recent years, it is urgent to establish an early warning and monitoring system for the two-level grassland pests in Jianli City. It is estimated that the construction fund will cost about 1 million yuan, including 200,000 yuan at the municipal level. The 8 flag areas are respectively 100,000 yuan, and the local government is required to solve it.
The total of the above two total needs for prevention and control funds is 7.05 million yuan, of which 3.2 million yuan is required for local supporting funds. The occurrence of grassland pests often has a certain suddenness with climate change, and the pest control drugs and funds must have a certain proportion of advance reserves in order to prepare for the timely release of sudden pests.
