Sowing method of swallow grass

Sowing time:

Under normal circumstances, we can sow seeds in spring and autumn. If we choose autumn, we'd better do it from late August to early September, not too late, or the temperature will be very low.

Seed collection and processing:

Around June, we can begin to collect seeds, which should be collected in time, otherwise the fruit will crack when it is too ripe. They can be dried and threshed in July. When choosing the seeds to be planted, choose the big, healthy seeds so that they have a higher chance of survival.

Sowing place:

It is better to be exposed to scattered light, not to be exposed to too strong direct light. In addition, we should also take into account the soil quality, which is rich in humus, and drainage performance is also an important factor. There are also some requirements such as looseness.

Sowing method:

We usually choose the method of direct broadcast to sow seeds, and the spacing is generally controlled at about 25 to 30 centimeters. Sow the selected seeds evenly, and then control the surrounding factors in a suitable state, such as temperature. Considering the suitable temperature for seed germination, the temperature near the soil is generally required to be around 15 degrees. If the sowing temperature in autumn is relatively low, pay attention to take appropriate measures to keep warm.

After waiting for about two weeks, we can observe the seed germination. Next, when it grows two or four true leaves, it can be transplanted. When four or seven true leaves grow, they can be planted.

Conclusion: this is the way to sow swallow grass. If you like it, please try it yourself.

[expert answers]

Swallow grass, also known as cat's eye, pigeon flower, big flower swallow grass, chicken claw lotus, Coptis chinensis and so on, is a common ornamental flower in life. Swallow is a taproot plant, like light, cold tolerance, fear of heat, reproduction is mainly direct seeding, transplanting needs the main root system. The editor of the first Agricultural Economics has sorted out the planting method of delphinium grass for you below:

● sowing: delphinium can be sown in spring and autumn, but must be sown in mid-September if sown in autumn.

● maintenance: delphinium must keep the soil moist after sowing. The easiest way is to cover some grass and gradually remove the mulch after emergence.

● change basin: when Swift grass grows 2 true leaves, it needs to take soil and transplant it in a small basin, wait for the seedling to grow up and then change the basin again.

● watering: when changing pots, dry manure is applied as basic fertilizer. In order to prevent the plant from growing too tall, paclobutrazol of 5000PPM can be applied once, or 1500PPM for a long time, once every half a month until budding. To water swallow grass to master between dry and wet, flowering should be appropriate more watering, do not make the soil too dry.

● fertilization: the eye fertilizer was applied once every semimonthly during the growing period of delphinium, and the phosphorus and potassium fertilizer was applied 2-3 times before flowering. The soil is kept moist during the flowering period, which can prolong the flowering period. According to the growth status of delphinium, cake fertilizer and water are applied 1-3 times a month.

● height control: after swallows are changed, paclobutrazol can be used to control the height of the plant. The specific method is to apply 0.5% paclobutrazol every 2 weeks.

● seed harvesting: the seeds of delphinium are mature from August to September, because the seeds mature first if they blossom first, and the fruit will split naturally after ripening, so they should be harvested in time to avoid scattered.

● diseases and insect pests: black spot, root neck rot and chrysanthemum leaf blight nematode disease are common in Swift grass, which damage leaves, flower buds and stems. When the disease occurs, the diseased plant is cleared in time, burned centrally, and sprayed with 50% methyl topiramate wettable powder diluted 500 times. The common pests of swallows are aphids and nocturnal moths, which are sprayed with 2000 times diluted 10% deworming EC.
