The wheat seedling stage refers to the vegetative growth of the long leaves, long roots and long pods before the wheat is sown and the wheat is grown and jointed. The wheat seedlings will experience a severe winter, often resulting in some abnormal seedlings due to poor quality of cultivation and poor management, which will seriously affect the wheat yield. If measures are taken early, they can still be converted into normal wheat seedlings. The following describes the formation of several abnormal seedlings and control methods:
1. Deep sowing seedlings. Due to more stalks in front rake, the rotary cultivator cuts uneven grass during ploughing and encounters heavy rain after sowing. It is easy to cause excessively deep burial in the grass with less or no stalks, and the top soil is compacted and the emergence is slow, even Wheat seedlings do not grow normally, or have fine stems, small leaves, sharp yellow leaves, few plants, and few pods after emergence. This situation should occur immediately when estrus is appropriate. Penetration promotes timely emergence and delivery.
2. Seedlings. When the seeding rate is too large and the seeding techniques are not refined, seedlings of seedlings often appear after sowing. The technology of arable land is not good, and the soil is not broken, and there are many dumpings; or the steps are uneven when sowing and the seedlings often appear in slow walking areas. To prevent this from happening, one must master scientific and reasonable sowing rates and determine the seed germination rate before sowing. The second is the fine preparation of land before sowing, and strive to crush the soil particles. For seedlings that have been seeded densely, cultivator techniques are used to remove excess seedlings as soon as possible.
3. Li needle seedlings. Poor seeding quality, too much seeding, too deep sowing or soil preparation before sowing is not fine, severe pressure seedlings after sowing suppression are easy to form a needle seedlings. In addition, in order to prevent the wheat seedlings from being frozen, the soil-fertilizer is used to cover the wheat seedlings, and the cover is thick, and it is also easy to form a vertical needle seedling when it rises in the spring. The needle-shaped seedlings are needle-shaped, with fewer tillers, fewer leaves, and the wheat seedlings are fine and long in shape, and do not form enough tillers. In order to prevent the emergence of needles, in improving the quality of the soil preparation and grasping the appropriate sowing volume, it should also pay attention to grasp a reasonable sowing depth, generally 3-5 cm is appropriate, to prevent too deep and shallow. Regardless of the cause of the establishment of the needle-needle seedlings, the soil must be sowed and the cultivator remove excess wheat seedlings. And promptly counter-fed seedlings were fertilized and watered to allow the needles to grow vigorously as soon as possible. Fertilization should be poured 2% -5% urea or diammonium phosphate solution.
4. Dew seedlings. Covering the soil or planting wheat in paddy fields, or due to mechanical failure, etc., easily expose seedlings. Dew-seedlings are prone to frost damage, they are easy to fall down, they are easy to blight in the later period, and they are easy to produce phytotoxicity when using herbicides. The method of prevention and control is to cover the soil as soon as possible. For interplanting wheat, a large-sized coulter can be installed in the middle of the rotary cultivator, and the sewer can be rotated to open the trench and cover with the fine earth formed by the trench.
5. Deficiency of seedlings. Mainly the soil moisture is not good, or uneven ground, uneven watering; Wheat germination rate is not high, mixed with uneven; å·Large and underground pests caused by the harm. General wheat ridge 15 cm below no seedlings are seedlings; wheat ridge above 15 cm without seedlings is broken ridges. Preventive measures: First, fine land preparation, land formation. The second is to sow the plant. If the land is not planted when sowing, it must be watered 1 week in advance, and sow when the water is suitable. The third is to do a good germination test wheat seed, germination rate of less than 95% do not use wheat seeds, seed dressing before sowing should be uniform. The fourth is to prevent and control underground pests in a timely manner.
6. Wang long seedlings. When the temperature is too high and the sowing is too early and the fertilizer and water are excessive, the pre-winter wheat seedlings are often prosperous. This situation will reduce the anti-freezing ability of wheat seedlings, reduce the rate of tillering and spike formation, and it is prone to premature aging and lodging in later stages, which is not conducive to high yield. In wheat fields with prosperous tendencies, timely repression should be carried out before winter, deep-rooted cuttings and roots should be applied, and appropriate amounts of paclobutrazol should be sprayed to prevent the jointing before winter, to minimize or not apply Miaofei, and to minimize the use of wax fertilizer. Seasonal panicle fertilizer.
