The planting method of gourd in the process of planting gourd in ancient China

Soak the seeds in 55 degrees water for 15 minutes, then 30 degrees water for 24 hours. Put it on warm water for seven days (without contact) and plant when the tip is split. Then plant it in the soil and turn to 18 degrees when the seedlings come out to 2 / 3. Selection of stubble and soil preparation 1. It is best to choose Pingchuan and two depressions with good drainage and fertile soil; the field with irrigation conditions can be used. Corn, wheat, soybean stubble is better, avoid white melons, watermelons and other melons continue to stubble, the last crop using closed herbicides can not be planted. 2. In the early spring, the soil was topped and ridged, and the soil moisture was suppressed in time. The planting ridges are long-mouth ridges with a width of 90-130cm, and 8 empty ridges in the middle are also beneficial to weeding. Indoor sprouting 1, seed soaking variety selection, Japanese green calabash, soaking seeds in 40 ℃ warm water for 24 hours, then wrap the dried gourd just harvested with gauze and open the soaked seeds. 2. Sprouting with a wooden trough or ordinary basin, padded with a layer of sterilized sawdust or sand, and then covered with gauze, the soaked seeds are evenly placed on the gauze, covered with a wrenched new towel, covered with a curtain, covered with a quilt, and dusted with a new brush twice a day. Don't brush too much water to prevent stagnant water in the seed coat. The budding temperature is generally 25 ℃ 28 ℃, not lower than 25 ℃, and the highest is not more than 32 ℃. 3. It is required to pick out the budded seeds every day, put them in another basin and put them in a cool place indoors to control the growth of the buds and wait for sowing. Seedbed sowing 1. Prepare the seedbed to pad 8-10cm horse dung or crushed grass at the bottom of the seedbed, cover it with a layer of soil, step on it and flatten it. At the same time, disinfect with 70% prednisone, 0.3-0.6 g per square meter, and buckle the shed at the same time. After sowing the seeds, buckle the shed 2 on the seedbed and prepare the nutritious soil to select the soil that has not used herbicides such as Pushter, Dousulfuron, and so on, and sift it, and mix it with the screened mature farm manure at 7:3. 3. Sow the nutritious soil into a 10 × 15cm plastic bag, and put 30 grains of 20Mel diammonium at the bottom of the plastic bag as base fertilizer, fill it with squatting, cut the bottom corner of the bag or pierce 4 holes with a hole of 8-10mm at the bottom of the bag in order to penetrate water. Put the nutrition bag neatly on the seedling bed (gap 1cm), and pour enough water, after the topsoil is dry, wait for sowing, the sowing time is April 5-10. Stick a 3-4cm deep eye in the middle of the nutrition bag, put the budding seeds with the bud eyes down, and water the soil once.
