"The rice that we planted before the Spring Festival is now hanging heavily in grain, but it is now standing upright and swaying with the wind." Recently, many people in Beipo Market, Wancheng Town, Wanning City, Hainan Province The masses told reporters. The relevant person in charge of the Wanning Agriculture Bureau explained that the phenomenon of rice in the valley is related to the low temperature, and the quality of the sowing seeds is no problem.
Rice in the harvest season sings "empty city plan", the two scenes contrast
According to the reflection of the masses of the North Slope of Wancheng Town in Wanning City, the reporter visited the field. Standing at the edge of the field, I saw a green scene, but when the reporter walked into the field, I found two kinds of growing rice. The rice ear of a rice became golden yellow, and I could clearly feel the ear of rice when I touched it. The fullness of this full rice ear has been turned to one side; but the other rice ear is still green, straight and standing upright, swaying with the wind, feeling the obvious openness when touched, squeezed hard, part of it The ear of rice will flow out of the white juice, and the remaining rice ears will have nothing.
It has never been seen in the past few decades of planting, and it is suspected that there is a problem with rice seeds.
When the reporter visited, he met the old man Yin Chunzhong who nursed the rice in the field. He said that the 1 mu of rice paddy planted by his family was in the village of Wozi Village, Jiuzhuang Village Committee of the North Slope. He planted the “Tianyou 2169†rice variety, since he Since I was sensible, I have been planting rice for decades. I have never seen the rice ear of a large area of ​​rice being empty. He suspects that there is a problem with rice. Yang Huaguo, a villager of Xincun Village Committee, said that since the floods in 2010, the rice planted by his family has all been rejected. His 2 acres of land this year is also planted with "Tianyou 2169" rice, which is expected to be harvested. "It is tangible."
“Early rice†is likely to be “overwhelmed by the whole armyâ€.
Ouyang Linhai, a rice distributor in the North Slope area, said that he is operating a regular store. The “Tianyou 2169†rice variety is directly purchased from the provincial seeds. The purchase channel is absolutely formal. This rice has been promoted for 4 years and has never appeared. The large area of ​​the rice ear that has been formed is a hollow shell phenomenon. According to his rough statistics, if an acre of rice fields requires 4 kg of rice seeds, there may be hundreds of acres of rice in the north slope area.
The abnormal low temperature is the main cause in the second half of March, and the quality of rice seeds meets the standards.
The relevant person in charge of the Wanning Agriculture Bureau introduced that they received the reflection from the masses on April 25, and sent staff to the field to check and ask the experts of the seed station in Hainan Province to conduct the inspection. The reason is that the low solidity rate is mainly due to this year. The effect of abnormal low temperature in the second half of March, the booting stage of this batch of rice heading around April 5 is just in the meiosis stage of pollen mother cells, because the daily average temperature is lower than 20 degrees Celsius, affecting the normal development of stamens and pollen, pollen Granular malformation or content is not full, losing fertility, resulting in infertility, resulting in normal pollination, fertilization after heading, and the emergence of Shibuya. The quality of the seeds planted by farmers is in line with national standards.
Premature sowing of early rice is susceptible to low temperature, and it is good to shoot after April 15th.
Experts suggest that the early planting habits of early rice production in parts of eastern cities and counties in Hainan Province are susceptible to low temperatures. If this cultivation habit is not changed, with the frequent occurrence of abnormal weather, the risk of production reduction or even failure of early rice production is difficult to avoid. The local agricultural department should actively guide farmers to scientifically arrange the planting time of early rice, and the growth period is within 130 days. The variety should be planted after New Year's Day, and the safe heading period should be arranged after April 15th to avoid the low temperature effect of “Qingmingfeng†from late March to early April to ensure safe production of rice.
