How to cope with the large area of Winter Wheat last year?Agricultural and Rural Ministry responses

On July 14, the Ministry of Agriculture and Rural Affairs held a press conference to introduce the situation of the "Sanxia" production situation. Zhao Guangcai, a researcher at the Institute of Crops of the Chinese Academy of Agricultural Sciences, said at the meeting that last year's winter wheat was broadcast late. This year's wheat production start is unfavorable and a wave of twists and turns. The key is to scientific and disaster relief to respond to late broadcasts, let farmers know how to grow, scientific field management accurate guidance, let the farmers know How to promote it, technology has played an important role in the increase of grain production this year.

Zhao Guangcai introduced that in response to the large -scale broadcast of winter wheat in winter in the fall and winter of last year, the instructor of the wheat experts of the Ministry of Agriculture and Rural Ministry formulated a "four supplements and one promotion" technical solution, which is an important technical measure to keep the wheat area. Specifically: scientific selection, so as to make up for the night. Under the premise of ensuring safety and overwintering, guide farmers to choose high -yield varieties with appropriate precocious precocious, make up for the influence of delayed and insufficient temperature, shortening the fertility period, and ensure that wheat grouting and safe maturity.

Press conference on the Ministry of Agriculture and Rural Ministry.

Increase the amount of broadcasting and make up for it. It is the use of independent stalk cultivation technology, which is a key measure to achieve high -yield high yields for late wheat, relying on increasing the amount of broadcasting to ensure the group, so as to achieve the appropriate number of spikes needed for high yields. Improve quality to make up for late. Wheats in the evening must improve the quality of sowing and create a suitable environment for emergence. This year, the landscapes of the evenings in various places attach great importance to improving the quality of sowing, so as to be finely rectified, properly sow, and under the feet to ensure that the seedlings, seedlings, and seedlings are uniform.

He said that he guides farmers to appropriately apply bottom fertilizer to meet the needs of the early growth of wheat in the early stage of wheat; especially paying attention to the application of phosphorus fertilizer, promote the development of wheat root system and the growth of division, and increase the scoring rate. "One promotion" is to strengthen the field tube, mainly promoting. In the early spring management of wheat, fertilizer and water are required to advance together, promote the occurrence of division, increase the group, and then carry out fertilizer and water management depending on the situation to promote the conversion of weak seedlings.

Adhere to the "one main line, three obedience", and the hydration sowing guarantees seedlings. In response to the soil overwhelming, the soil is excessive, and the coordinates can implement the "one main line, three obedience" wheat humidifying sowing schemes. This is an important technical measure to ensure that the seedlings are neat and sowing all seedlings. "A main line" is based on the broadcast period. It is scientifically determined in the morning and evening of the broadcast period to scientifically determine the key indicators such as varieties, broadcasts, and fertilization. "Three obediences" means obedience to the broadcast period, the quality of the broadcast, and the volume of the broadcast. In the broadcast period, we must obey the emotions, guide farmers not to rush to sow, prevent mechanical crushing the soil, and the emergence of soil waste or destroying farming. Priority is given to the soil scattered entropy. When the soil of the farming layer is relatively moisture content of 70%-80%, the land is planted.

Zhao Guangcai also emphasized that he vigorously promoted integrated machinery, fertilization, and sowing machinery, reducing the number of mechanical entry operations, and creating good soil conditions for wheat seedlings. Also, the amount of broadcast must be obeyed. From the previous experience, the later the broadcast period is delayed, and the amount of broadcasting must be increased accordingly. Generally, after the appropriate sowing period, the number of broadcasts per acre will increase by about 1 catties per late broadcast. But the basic seedlings should not exceed the number of ears required for high yields.

In addition, in response to winter seedlings, it is generally weaker, guiding all places to do a good job of "four morning promotion", strengthen field management, and promote the conversion of seedlings. "Early in the morning" is to manage early, and the time of the field management from getting up early to return to youth is about one month earlier than usual. The "four promotion" is to increase the warmth to promote early hair, suppress the promotion of the green, increase the application of phosphate fertilizer, and promote the transformation of four measures to promote the transformation of the fertilizer and water transportation. Miao, through spring management to make up for the shortcomings before the winter.
