Starting from the seedlings, the following are the key points for the cultivation of autumn melons in small series, and the growers have a quick look!
Melon sowing and seedling preparation and preparation before planting, including matrix pre-wet treatment, substrate loading, seeding points, hanging wire setting, land ploughing, planting methods and pest control. The detailed points are as follows:
Autumn melon seedlings points:
1. Pre-wet the substrate, add about 1/4 pre-wet according to the volume of water, and the sensory index can reach a group by hand, and the degree of dispersal can be dissipated. After adding water and stirring, the pile is stuffy and the substrate is fully absorbed. After 15 minutes, the mixture is stirred once more. After the dry and wet is even, the tray can be filled.
2. The substrate is loaded, and each hole of the plug is filled with the matrix, and the false reality is consistent. After filling, use the excess matrix above the scraper hole to make the hole of the tray clear, and then discharge it neatly into the seedbed, surrounded by soil sand or fine soil;
3, using the on-demand method. First, press a finger with a depth of 1cm in the center of each hole of the plug. When seeding, use the scorpion to sow the seed in the hole. The bud tip is downward, and the seed is sown at each hole. After sowing, cover the substrate cover seed, about 1cm thick, by first sprinkling the pre-wet substrate, and scraping with a scraper.
4, after sowing, spray water to pour through the substrate, cover the white cloth or old sheets or newspapers on the tray to moisturize, remove the cover when the buds top the soil;
5. After sowing, the surface of the seedlings must be shaded with a sunshade net and ventilated around. The seedling trays are sprayed once a day in the morning to humidify and cool down. The first water spray is sprayed with a sprayer, and the sprinkler can be sprinkled with water later. In the greenhouse, the hanging vine wire is set at a height of about 2m from the ground, and the main wire of the east and west hangs is set to 5 lines. The 24th wire is suitable, and the north-south direction is set by the line spacing, and the 20~22 wire is suitable.
Key points of prevention and control of whitefly
667m2 with 80% dichlorvos 500m and sawdust 20L, stir and mix well, in the evening, place 1 small heap every 2m2 on the greenhouse floor, then close the greenhouse for 1 night, use dichlorvos to naturally smother the whitefly.
