How to solve the thirst of late rice seedlings at high temperature?

Zhejiang News Client reporter Lai Yichen Lu Xin correspondent Qiu Yunfeng

Editor's note: At present, Zhejiang agricultural production is in the critical period of summer tube and summer species. Continuous high temperature drought on crops and livestock and poultry growth will have a significant impact. Zhejiang News Client has launched a series of "fields at high temperature" series of observations, so stay tuned.

The scorching sun is now in the season of late rice. Recently, in Jiangtang Town northwest of Wucheng District, Jinhua City, the reporter met two frowning grain farmers in the field: the "veteran" Sheng Guiyou and the "recruit" Zhang Xiajun, who had grown grain for 17 years.

"The seedlings are thirsty, the ground is dry, and we are in a hurry!" The rain that could not be looking forward to became their common heart disease.

The farmland of the old Sheng family is located in the upper reaches of the irrigation area, accounting for unique advantages, but he still can't be happy. "When the reservoir was put in water, our upstream farmers raced against time, and did not sleep to attract water all night, so they could only support it." Lao Sheng said that the Jinlan Reservoir they rely on should first ensure that urban residents drink water, water release time and water release. They are limited.

Entering Lao Sheng's family farm, the reporter did not see the scene of the blue sky and white clouds reflecting the lush and lush water fields. Instead, he saw that the farmland that had just been inserted and pawred had bottomed out, and some seedlings became yellow. "For so many years, I have not encountered such extreme situations. I have a high temperature every day for more than a month, without the next decent rain." Looking at the seedlings fell to the ground, Lao Sheng couldn't show it.

"Your upstream situation is much stronger than our downstream." Zhang Xiajun, who was standing aside, couldn't hold it. He took the reporter to the 50 -acre fields in his home in the irrigation area. He saw that the soil in the rice field was dry, and the newly inserted late rice seedlings had died. "I pump water from the canal outside 200 meters with oil pumps, and the water of ten gasoline barrels is not enough." He frownedly stated that the conditions of this field irrigation facilities were relatively poor, and the cost of artificial pumping was too high. Watching the seedlings died.

What makes them helpless is that although farmers have insured the complete cost insurance of rice, the premise of fixed damage is that the seedlings must be inserted. The situation of dried rice seedlings like this cannot be claimed to restore losses.

The phenomenon of "long -term rain led to the lack of paddy fields" has occurred in many places in the province. In Wenling, Taizhou, Zhu Guocong, a large grain, also had the same trouble. "It hasn't rained for more than a month, and the river passing the river is almost bottomed." He said that due to the high temperature shortage during the mature period of grouting, the premature failure and the flat shell rate became higher; If it is difficult to replenish a large amount of hydration after insertion of the late rice seedlings, it will face the production of death seedlings.

Right now, all parts of Zhejiang are entering the sprint stage of "early rice grab and late rice grabbing" in the summer. But with it, for more than a month, large -scale, persistent, high -intensity rare high temperature weather. According to the provincial climate center data, since the start of the "double grab" on July 5, the average temperature in the province is 2.2 ° C higher than the year, and the extreme high temperature above 40 ° C is more than 60 % less than the year. The reporter learned from the Provincial Agricultural and Rural Plant Planting Department that at present, the single -quarter late rice is in the diversified period of the ears, and the late rice is in the diversion period. Continuous high temperature and drought will affect the differentiated diversion of late rice in a single season, leading to smaller ears type; even the late rice seedlings are easy to lose seedlings or even dead seedlings, affect early hair, and reduce the number of effective ears.

Conservation of irrigation is the "quenching" of farmland, and has become the focus of the work of helping farmers in various departments and departments. The reporter learned from the Agricultural and Water Center of the Provincial Department of Water Resources that the province's major and medium -sized irrigation areas have opened the "order style" to protect irrigation services, correct and improve the irrigation protection water supply plan, and organize personnel to carry out the maintenance and maintenance of irrigation facilities and equipment Keeping work, inspect whether the irrigation water is effectively remitted into the farmland.

How to use limited water on the blade? "We have built a number of high -efficiency water -saving irrigation projects. Advanced water -saving irrigation techniques such as pipe irrigation, spray irrigation, and micro -irrigation can effectively reduce the water loss of water transmission process and improve the efficiency of irrigation." The relevant person in charge of the office stated that Zhejiang is continuing to promote agricultural water saving and efficiency, and strongly guarantee agricultural production in the high temperature and dry years.
