How to fertilize wheat into green fertilizer and joint fertilizer? In the process of planting wheat, fertilization in different periods is different. For example, when wheat is green, the application of green fertilizer is mainly for strengthening seedlings, increasing seedlings, and preventing excessive internodes. It is necessary to decide whether according to wheat planting time and seedling conditions. Apply green fertilizer. In the jointing stage of wheat, the main purpose is to protect the ear and prevent the ear from being too long. It is required to strictly control the joint fertilizer according to the size of the field group. Therefore, today Xiaobian talks about the fertilization points of wheat and wheat to green fertilizer and joint fertilizer, as follows.
First, the rational application of returning green fertilizer
1. Wheat back to green fertilizer can promote the growth of wheat seedlings, mainly due to the increase of tillering of wheat seedlings, the increase of wheat seedlings in the field, and the promotion of weak seedlings and seedlings transformation. In production, the fertilizers are mainly applied to weakly seedlings and under-populated fields. When the wheat population in the field is too large, the application of the green fertilizer should be strictly controlled to prevent the group from being larger.
2. In the early stage of wheat returning to green, more than 300,000 fields per mu of stalk seedlings, if the wheat leaves are normal, generally do not apply green fertilizer; if the wheat saplings are yellowish, the fertilizer can be applied, but it must be strictly controlled. The dosage is generally 5-10 kg of urea per acre according to the pre-fertilization of wheat.
3, in the early stage of rejuvenation, the amount of acres of stems and seedlings less than 300,000 fields, it is necessary to decide whether to apply green fertilizer according to the sowing time and seedlings. Fields that are planted early, have less emergence or have poor growth during seedling stage, and are properly fertilized to promote population growth. The temperature of the late sowing wheat was low. On the one hand, the release of fertilizer was slow. On the other hand, the germination of wheat was late, the roots were born late, and the amount of base fertilizer applied to the soil was absorbed less. These fertilizers were slowly absorbed until the spring temperature rose. Absorbed in large quantities. These fields are generally not allowed to apply green fertilizer unless the wheat seedlings show signs of falling yellow.
Second, the rational application of joint fertilizer
1. In the early stage of jointing, the field main stem and the big branch above the three leaves have more than 350,000 fields per acre. The application of joint fertilizer should be strictly controlled. The size of the joint can be determined according to the size of the population. Cm), the length of the second section (3-6 cm) and the application of the panicle fertilizer, the larger the group, the more prosperous the field, the more time to apply the panicle fertilizer.
2. In the field of jointing stage, the main stem of the field and the large tiller of 3 or more leaves are less than 350,000 per acre. If the number of small tillers is small, the fertilizer should be applied early to increase the number of tillers and promote the early age of jointing. 2.5 leaves around the "shake the tiller" into the ear. If the color of the wheat seedlings is normal and does not fall yellow at the beginning of jointing, it should be divided into two times when fertilizing, and a small amount of fertilization should be applied at the beginning of jointing to promote the "shaking and splitting" into the ear, and the second section is basically fixed length and the third section is elongated. Fertilize to promote the formation of large ears. If the color of the young wheat leaves is yellow and the seedlings are weak at the beginning of the jointing stage, the seasoning panicle fertilizer can be applied at one time.
3. In addition to the application of nitrogen fertilizer, the jointing booting spike can also increase the application of potassium fertilizer, which is conducive to stem filling and differentiation of young spikes. Generally, 5 kg of urea per mu is applied, which can be applied before and after raining or during rain.
