High-quality special wheat cultivation notes

Because high-quality special wheat has its strict quality index requirements, there will inevitably be more stringent requirements in the implementation of planting and cultivation management. Specific attention to the following points:

1, must implement careful formula fertilization. Formula fertilization not only increases the significance of yield, but also has the significance of improving quality. For high-quality special wheat, the unreasonable ratio of fertilization will inevitably bring adverse effects on quality indicators. For example: nitrogen deficiency will reduce the protein content; excessive nitrogen fertilizer or excessive weight in the early stage, phosphorus and potassium fertilizer deficiency, lack of trace elements. Inevitably lead to poor late filling, affecting many quality indicators. Therefore, the cultivation of high-quality special wheat must be carefully implemented formula fertilization. Requirements: about 15 kg of nitrogen, 40% of base fertilizer, and top dressing, followed by fractional application (joining at the jointing stage, heading stage, twice before top dressing), about 10 kg of phosphorus pentoxide, and about 7.5 kg of potassium oxide. Fertilizer 2.5 kg (zinc, boron, manganese 2:1:2). Phosphorus, potassium and micro-fertilizer are applied once. This formula farmer is more difficult to implement, here to recommend two "formula fertilizer", one is "ferrer" special fertilizer, the second is "BB fertilizer."

2. Must strictly control group development. In wheat cultivation, if the population is too small, high quality can be obtained, but the yield is reduced; if the group is too large and the medium-term canopy closure, it will inevitably cause one of the three conditions of late lodging, greediness, and greed-type premature grogginess. Well, the grain plumpness is poor and the bulk density is reduced, and the processing quality will be seriously affected. The main reasons for the large groups are two key links. One is that the sowing density (ie, the starting point of the group) is too high, and the second is the mismanagement of water and fertilizer. In the current promotion of a few high-quality special wheat, within the scope of appropriate sowing, the basic seedlings can be 120,000-22 million, and high-fertilizer land needs to be properly reduced. At the same time, water-saving cultivation techniques that promote proper late planting and appropriately increase the amount of sowing are also advocated.

The key period for water and fertilizer management to control the population is the first watering and top dressing in spring. The principle of high-yield cultivation and management of "rich-bottomed, pre-controlled, and post-promoted" wheat is more suitable for high-quality special wheat and requires more rigorous control. Under the conditions of plantar plantar, plantar fat, fine soil preparation, and high quality sowing (including sowing date, sowing volume, sowing depth, row spacing, etc.), the water is controlled in the early spring (returning from the green period) and the jointing period is implemented for the first time in the spring. Fertilizer is the basis for ensuring the stable development of high-yield wheat in the late-stage population. Such management can promote the early development of the roots and full development, the development of the root system, the rapid polarization of the group, to avoid the closure of the medium-term, improve ventilation and light conditions, maintain the higher root activity in the later period, the pole is shorter and strong, spikes neat, improve Grouting strength, effectively overcome lodging, greediness or greed-type premature aging, both high yield and high quality.

3. Strengthen disease prevention and control. High-quality special wheat has only normal grouting and full grain is expected to meet the requirements for special quality indicators. Strengthen plant protection measures and reduce the occurrence of pests and diseases to achieve this goal. In addition to the original powdery mildew disease in recent years, the occurrence and development of fungal diseases such as root rot, sheath blight, leaf blight, and head blight have become increasingly serious. Therefore, in addition to conventional pest control and grass control, plant protection measures must be combined with pest and grass control to strengthen disease prevention and control. Three applications of bactericide are required. In combination with the control of underground pests and the sowing of fungicides, it is best to use seed coating agents for seeds, in combination with weeding and fungicides at the beginning of the period, combined with the addition of fungicides at later stages of the disease.

4, pay attention to miscellaneous and inferior. Although it is not a seed field, it is very important to ensure the purity of dedicated wheat, and it is imperative to remove the strains and mutant strains.
