The use of seeder to broadcast live must have the advantages of saving labor, saving money, and reducing the occurrence of virus diseases. According to the experiment, live seedlings can save about 6 workers per acre, reduce labor costs by 150 yuan, and apply less fertilizer once. Live broadcast can also enhance the resistance of mustard and reduce the incidence of viral diseases by more than 15%. The specific live broadcast technology is as follows:
Prepare before broadcast
When ploughing is suitable for flooding, plowing and soil preparation should be done. The soil should be fine. If the soil block is large, it can easily lead to unstable walking of the seeder wheel, spreading the seeds to one side and causing uneven seeding.
Applying basal fertilizer in the preparation of Mushi 25% compound fertilizer 50 kg, or 45% compound fertilizer 30 kg, or organic fertilizer 100 kg spread.
Spraying herbicides After fertilizing soil preparation, spray acetochlor, 50 grams per acre for soil treatment to prevent weeds (seeding after 1-2 days).
sowing
Sowing time is late October. With the new species of the year, the germination rate is required to be above 90%. When sow hand-held device handle, slowly walk forward, per mu sowing volume of 70-80 grams, can also be live broadcast by hand.
Seedling management
Immediately after the seedlings were removed, Pengtou was removed and pests and diseases were prevented. It is prone to epidemics due to high humidity and high humidity, and can be sprayed with 1200 times of “killable†medicaments; insect pests mainly include aphids and diamondback moth, etc. The mu is sprayed with 25 grams of Jiagenjin 1500 times liquid to prevent and cure. When the seedlings grow to the 3-leaf stage, Dingmiao and Miao Miao can be carried out (for transplanting the land), and the spacing is 12 cm and 20 cm.
top dressing
For the first time around December 20th, 45% compound fertilizer was applied 30 kg before rain. The second time in late January, 15 kg of urea and 5 kg of potash were applied before raining. The third time in late February, 20 kg of urea was sprayed before the rain.
Disease prevention weeding mustard black spot and white rust can be used carbendazim 800 times solution plus copper 1500 times liquid control. On the basis of the previous soil treatment, when the weeds grow again and grow to a certain degree, they can be controlled by using grass or glycyrrhizae, with a dosage of 50 grams per mu.
