Because some plants will sow early, and some will sow late. But most of the time is in spring, when the agriculture is busy, it is necessary to sow and cultivate seeds in order to improve the yield better.
Four-season farming is: spring farming includes ploughing, sowing and seedling raising, furrowing and water management, mulberry picking, topdressing and spring water irrigation. Summer farming includes sowing, transplanting, weeding, drought and disaster prevention, pest control, water and fertilizer management, etc.
Autumn farming includes irrigation, weeding, topdressing, pest control, harvesting and threshing. Winter farming includes seedling raising, deep ploughing, fertilizer accumulation and maintenance of agricultural machinery and equipment. From south to north in China, the cultivation of crops is different, and the agricultural activities are different all year round.
Sowing method
1, broadcast
The common methods are simple to operate and suitable for most factories. Seedbeds should be prepared in advance when sowing, and plots should be arranged according to plant growth habits-generally, the soil should be breathable and fertile. Seeds should be full, mature and free from pests and diseases. When ready, spread the seeds evenly on the soil surface and cover them with thin soil.
2. On demand
Sowing on demand, also known as hole sowing, is to drill holes at regular intervals on the treated land. The advantage of sowing on demand is that it can ensure the plant spacing and sowing density, save seeds, and facilitate seedling raising and intertillage. It is suitable for corn, cotton, sunflower and other crops. However, this method requires high seed quality, and the seed quality can ensure the germination rate.
3, drilling
The drilling method is to open a ditch with appropriate size on the sorted plot, control the row spacing according to the habits of plants, then scatter the prepared seeds in the ditch and cover the soil after sowing. Perforation can ensure better ventilation and light transmission, and is also convenient for weeding, thinning and management.
4, mechanical sowing
The so-called integrated sowing method is to sow with a seeder, which integrates fertilization, sowing and spraying. It saves time and labor, and greatly improves the planting efficiency. Now the integrated sowing method is widely used in agricultural production.
