“Rice does not have to be soaked in water, there is no clear water layer, and rice can grow well.†Ningxia farmers who learned the new technology of rice water-saving control and irrigation finally changed the traditional concept of deep-water flooding of rice. . According to the data, half of the irrigation areas in Ningxia Yellow River Irrigation Area have implemented water conservation and irrigation control this year. In 2001 alone, 220 million cubic meters of field water were saved, and the amount of water lost from the canal system reduced the amount of Yellow River water throughout the year. Nearly 400 million cubic meters. At present, Ningxia Irrigation District has more than 100 million mu of rice. Rice is a high-water-consuming crop. Ningxia has long used large-scale, large-row and deep-water flood irrigation methods. The water used per mu is as high as 1,700 to 2,500 cubic meters, which makes 100 million mu of rice water account for 34% of Ningxia's total agricultural water use. This consumption of water is extremely inconsistent with the increasingly scarce reality of the Yellow River water supply. To this end, Ningxia has introduced the Rice Water Saving and High-yield Control Irrigation Technology from Hohai University. This new technology has rapidly developed from 24 acres of demonstration land in 1998 to 510,000 mu in 2001, and the area of ​​promotion has accounted for nearly half of the area of ​​rice in Ningxia. Rice paddy fields with controlled irrigation technology have been promoted. The average water saving per mu is 446 cubic meters, and the water saving rate has reached 39%. From 1998 to 2000, 25.4 million mu was cumulatively promoted, and nearly 200 million cubic meters of Yellow River water was infrequently cited. In 2001, the number of Yellow River water was nearly 400 million cubic meters. So, will rice be reduced by reducing the amount of water? The joint survey by the relevant departments showed that the average per mu yield of control-irrigated paddy fields was 660 kilograms, which was 30.1 kilograms higher than conventional flood irrigation, and the increase rate was 4.7%. Due to the reduction of the number of irrigations and the amount of irrigation water, the farmers reduced the water fee expenditure by 8.9 yuan per mu, and in addition, the labor cost per mu was equal to 16 yuan. The total amount of mu is reduced by 61 yuan, and the economic benefits are considerable. Chinese Agricultural Editor
An insulin pen injector is a medical device used by people with diabetes to inject insulin into their body. It looks like a pen and has a cartridge filled with insulin that is inserted into the device. The pen has a dial that can be turned to select the desired dose of insulin, and a button that is pressed to inject the insulin into the body. Insulin pen injectors are convenient and easy to use, making it easier for people with diabetes to manage their insulin therapy. They are available in both disposable and reusable forms, and can be used with different types of insulin.
