How is mustard high-yield planting? The leaves of mustard can be used to pickle pickles, seeds and whole grass can be used as medicine. It has the effects of relieving phlegm, relieving asthma, reducing swelling and relieving pain. The seeds can be ground into mustard (flavoring) and can also be extracted with mustard oil. The planting benefit can be said to be very It’s not bad. Next, Xiaobian talks about the high-yield planting technology of mustard greens from the points of mustard breeding, field management, and pest control. I hope that everyone can help.
1. Breeding method, artificial cultivation
Breeding method: collecting both wild and artificial cultivation;
Artificial cultivation: two types of open field cultivation and protected area cultivation.
2, site preparation requirements
The land should be leveled and neat, and deep sorghum (2.5m wide) should be achieved, which is conducive to the accumulation of water.
3, sowing
(1) Sowing period
Spring cultivation time: in late February;
Summer cultivation time: from early July to late August;
Autumn cultivation time: from early September to early October;
Generally speaking, it is mainly cultivated in autumn.
(2) Seeding rate
Spring sowing: the seeding rate per 667m2 is 1.5-2kg;
Summer sowing: the seeding rate per 667m2 is 3-4kg;
Autumn sowing: The seeding rate per 667m2 is 2-3kg.
(3) Seeding method
a, mustard seeding: the use of dissemination, it should be noted that the spread should be even;
b. After sowing, the soil is gently pressed to the surface, so that the seeds and the soil are in close contact, which is beneficial to the seed to absorb water and emerge early.
c. Mustard seeds sown in summer, watering the land one or two days before the land preparation, and then planting the ground;
d. Seeding can only be carried out after germination in the environment where the seeds harvested in the year need to be placed 2-7.
Second, field management
1, reasonable fertilization
(1) After the autumn sowing, the mustard will emerge in 3-4 days, and the mustard after spring sowing will emerge in 6-15 days.
(2) When the seedlings grow 2 true leaves, the first fertilization is carried out, and 1000 kg of 0.3% urea solution is applied per mu.
(3) The second top dressing is carried out 7-10 days before the mustard harvest, and then once every harvest.
2, watering at the right time
(1) Watering time: It is suitable for morning and evening.
(2) Watering principle: light pouring, frequent pouring, can not be watered at one time.
(3) Since the mustard seeds are small, they are easily affected by soil moisture, so pay attention to watering and moisturizing before emergence.
3, timely weeding
The mustard seeding planting will make the weeds mixed with mustard, so we need to combine the harvest to remove the weeds.
Third, pest control
1, the main pests and diseases of mustard: downy mildew, aphids.
2, pest control: the use of integrated prevention, the main operations are as follows:
(1) Clearing the ditch to prevent water accumulation and timely weeding to ensure the ventilation and light transmission of the plants;
(2) Downy mildew prevention and treatment method: using 75% chlorothalonil 600 times solution or 72% gram dew 600-800 times solution spray control;
(3) Control methods for mites: control with acetamiprid or pyrethroid pesticides.
