Trench ditch planting and seeding techniques
1. Rotate
Spread chemical fertilizer, organic fertilizer and trace element fertilizer into the ground first, evenly. Then use a rotary tiller to break up the soil and make it thin. Be careful not to rotate it to the two sides of the greenhouse. Leave 30 cm on each side without rotary tillage. In order to prevent the bottom of the iron pipe from shaking.
2. Ditching
Note the 7-meter wide shed, measure 175 centimeters inwards on both sides, this is the position of the ditch (ditch centerline), the two shed heads are inserted according to the position of the ditch at 175 centimeters, and the marker is inserted so that the north and south There are 4 marks in total.
3. Grass filling
After the ditch is opened, it is necessary to fill the ditch with straw, which is the straw of the crop, corn stalk, peanut seedlings, wheat seedlings. Generally, corn stalks can be used. Corn stalks are the easiest to obtain in rural areas. Slow ditch. Compress the corn stalks one by one, about half the length, and spread the layers evenly to cover the ditch. The straws are spread about 30 cm thick. In this way, in the cold winter, the temperature of the soil can be increased and the growth of melons can be laid. basis.
4. Covering soil
Cover the soil with a thickness of 15 to 20 cm, bury the corn stalks in the soil, and form two ridges from north to south. The bottom of the ridge is about 1 meter wide, the top of the ridge is about 80 cm wide, and the height of the ridge is about 20 cm. It is convenient for watering irrigation ditch.
5. Irrigation ditch
Irrigate the ditch from the beginning with sprinkler irrigation. The purpose of the ditch is to penetrate the corn stalk with a water tank, because the corn stalk will heat in the soil after irrigation, and the soil temperature can be raised well in winter. Generally, a section of sprinkler irrigation of about 10 meters and a 150-meter-long greenhouse, 15 sections of sprinkler irrigation is enough. Water from one end of the shed to the other, when the two melon ridges are fully watered.
How to sow after ditching?
Direct seeding sows the seeds into the soil and covers 3 cm of thin soil to keep the row spacing around 60 cm and the plant spacing around 50 cm. After sowing, maintain the temperature at about 30 ℃, which is conducive to seed germination. If the temperature conditions are not reached, the film can be covered, and the price temperature is maintained at about 20-25 ° C during the emergence stage, and it is not conducive to plant growth below 10 ° C.
After the construction of the melon greenhouse, the first point is to open the trench and do a good job to lay a good foundation for subsequent planting. In addition, pay attention to the time and method when planting, so as to grow good melons.
