In northern China's spring, it is windy and rainy and has a large amount of evaporation. It is the driest season of the year. Therefore, the majority of farmers have accumulated a lot of experience in drought-resistant and safe planting of spring crops, which are summarized as follows:
The watering point first digs the nest, waters the nest, then spots the seed in the nest and covers it with soil.
Ditch planting first plowing a deep ditch, the seeds sowed on the wet soil, and then gently shoot, and then cover a layer of fine dry soil, in order to protect the lotus, suitable for gardenia, millet and other crops.
The seedlings are transplanted and transplanted in the land near the field. The seedlings are transplanted after rain and are suitable for large-grain seed crops such as melons.
Drain the seeds 3 to 4 days before sowing, soak the clods and press them once with a stone pestle to sow in the morning at the time when the ground is low tide. Follow the broadcast to prevent running ranch. After 2~3 days, make the water gradually Move to germinate and emerge. It is suitable for plots with large loess and poor bottom.
Top Ling sowing in the soil began to thaw, wet soil layer up to about 6 cm when grabbed the early sowing, the seeds sowed on the frozen soil layer, make full use of the bottom of the seed to promote seed germination, suitable for lentils, peas and other crops.
Put the straw into the corn stalk or sorghum stalk into a short section of 3 to 5 cm long, soaked in water, while germinating the seeds in warm water, so that when the seed radicle just break the seed coat, remove the straw and put it in Seed, then seed. Seed germs draw water from the straw and sprout quickly.
Immersion seed germination will soak the seeds, until the seeds suck enough water for germination, remove, cover with sacks and other boring species, the next day can be sown, soil moisture is very poor, unconditional artificial watering plots, not suitable This method.
