According to the survey of summer maize planting in the Plantation Management Section of the Agriculture and Animal Husbandry Bureau, the planting area of ​​summer maize in the county continues to increase this year. The proportion of shovel planting area increases, the corn sowing period is relatively late, the density is basically suitable, the temperature is suitable, the rainfall is abundant, and the yield is high. The harvest has laid a good foundation.
I. Sowing date and analysis of seedling situation
1. The sowing date is not concentrated, and the long sowing period of the sowing time period is relatively late. Due to the rain during the wheat harvest this year, the wheat harvest period has been greatly delayed, and the farmers have the habit of interplanting. Since May 25, the wheat and wheat intercropping has appeared in the county. By June 5, the interplanting area reached 250,000 mu, and all the watering after sowing. . Due to the delay of 3-5 days in wheat harvest, another heavy rain fell on June 16, June 18-21 was the concentrated harvest period of wheat, and from June 6 to 15, the corn intercropping area accounted for 300,000 mu. The planting area of ​​the affixing is about 50,000 mu, of which the integrated planting area of ​​seed fertilizer is about 30,000 mu, and the corn planting task is completed by June 21.
2. The planting area continues to grow, which is conducive to improving the total corn production in the county. According to the survey, the county's corn planting area this year is 601,900 mu, an increase of 35,000 mu compared with last year, which is conducive to the total corn production in the county.
3, suitable temperature, is conducive to the growth and development of corn seedlings. This year, the average temperature of our county in June was 27.7 degrees, 0.7 degrees higher than the same period last year. The highest and lowest single-day average temperatures were 30.8 degrees on June 30 and 22.9 degrees on June 25, and there was no high temperature above 35 degrees after sowing. The temperature was suitable, which was conducive to the growth and development of corn seedlings.
4, sufficient precipitation, soil moisture is suitable for corn seedling growth. On June 16th, another heavy rain fell, the rain was full of sensation, and the seeds were all coated to the ground, laying a foundation for ensuring the quality of the emergence. In particular, there are two large-scale rainfalls after the sowing of corn. The abundant rainfall makes the soil moisture sufficient, and the soil moisture is suitable for the growth and development of corn seedlings.
Second, seedling management technical advice
According to the climatic characteristics and sowing conditions of this year, the management of corn seedling stage should focus on increasing seedling fertilizer and promoting the rapid growth of seedlings, and take the time to manage the seedlings, seedlings, seedlings, and seedlings. The specific management measures are as follows:
1. Check the seedlings and make up the seedlings. After the emergence of the corn, check the emergence of the seedlings in time, and the lack of seedlings and ridges should be transplanted in time. It is best to replant the 3-4 tablets when the leaves are visible. Replenish the seedlings before the seedlings are available. It is best to replant in the afternoon or on cloudy days. Watering should be done immediately after transplanting to reduce the seedlings and improve the survival rate. When the amount of seedlings in the field is not large, in order to reduce the time of slow seedlings, measures to stay close to the two plants can be taken to fight for agricultural time.
Machine-cast corn field, early seedlings, late seedlings, for dense seedlings, in 3-4 pieces of visible inter-leaf seedlings, 6-7 pieces of leaf-fixing seedlings, interplanting plots can be fixed at 5-6 leaves once, when seedlings are fixed Pull out weak seedlings, seedlings, diseased seedlings, and mixed seedlings, and select the seedlings in the same size to achieve a reasonable seedling density. The seedling time should be appropriate, and the seedlings are too early to find the seedlings, seedlings, and weak seedlings; the seedlings are too late to cause the seedlings to be crowded and consume nutrients, and it is easy to form yellow seedlings and weak seedlings.
2, timely fattening to promote seedlings and long. If the bottom fertilizer is insufficient or the fertilizer is not applied, it is necessary to make up the seedling fertilizer in time. Sticking to the sowing plot, the urea can be applied about 5-10 kg per mu, and the intercropped plot can be seen before the 6-8 leaves of the leaves at the seedling stage, about 5 kg of potassium chloride and 5-10 kg of urea.
3, timely pests and diseases. Maize seedlings are prone to pests and diseases, such as rough disease, gray planthopper, armyworm, thrips, and golden worm. This year, some parts of the county, Hummer and the second point, the night moth occurred more seriously, and it is urgent to strengthen prevention and treatment. In particular, chemical weeding should be selected as a herbicide, and it should be used strictly according to the period of use, dosage and operation method to prevent phytotoxicity.
