To change the soil is to remove the old soil, replace it with new soil, and add the base fertilizer, sort out the roots, cut off the roots, rotten roots and long roots. To enlarge the pot diameter is to replace a pot with a larger pot diameter to ensure that the root system has sufficient vegetative growth space(gallon pot). When turning over the basin, it should be slightly dry. When the basin is removed, the bottom of the basin is turned to the sky, and the outer wall of the basin is tapped with the palm of the hand, and the root group will come out. Be careful to shake off the old soil after removing the pot, and cut off the rotten roots, the dead roots and the long roots.
Potting soil should be rich in organic matter: pottery soil with high organic matter content, high fertility, long fertilizer efficiency, good water retention and fertilizer retention, and can release all kinds of nutrients in a balanced manner during cactus plant growth, and promote cactus normal. Growing. The soil of the potting soil should be loose: the potting soil should have a suitable pH(black plastic plant pots): the cactus prefers to grow in a neutral or slightly acidic soil environment, and the optimum soil pH should be around 6-7.
After germination, spread the flat plate, about 1000 per plate. After exposing the true leaves, spray with 2000 times of fertilizer to focus on preventing the disease. When the true leaf grows to the size of the thumb cover, spray the dwarf king or chlorophyll to control it again(plug trays). Eggplant rootstock 5 leaves 1 heart, scion 4 leaves 1 heart, stem diameter 0.3 ~ 0.5cm, grafting during semi-lignification. Grafting must require skilled grafting workers, thorough disinfection, healing period of about 7 days, the film bottom temperature should not be higher than 32 ° C, night temperature should not be lower than 15 ° C.
The device has a simple structure, low cost, and is free from restrictions on electric power or power driving, and the use range is expanded to meet the operation needs of small farmers. However, for large-scale nursery growers, the efficiency is low and the labor intensity is high. [Jishan Huayao] provides a new type of hole puncher based on parallel four-bar mechanism. By rotating the hole plate, the pressure pin on it is used to realize the pressure hole. For different sizes of trays, change the number of pressure plate and pressure pin to match.
Not only meet the needs of small farmers, but also adapt to the needs of large-scale seedling planting. The GS series needle-type seedling seedling seeding device produced by SEEDERMAN of the United States has the advantages of high seeding precision and easy operation(plug trays wholesale). The single-row pressure point device of the matched pin type precision seeding machine adopts air pressure driving, and relies on the cooperation with the crawler belt on the lower working table to realize the effect of moving the pressure hole one row at a time. The pressure point is good for neutrality and the efficiency is 300. Disk / h.
Traditional seedling substrates are usually prepared from grass charcoal, vermiculite and perlite in a certain proportion. However, peat is a non-renewable resource, and rational development of cheap and practical matrix substitutes has become a hot spot in agricultural and horticultural research. Coco peat is a new soilless culture material made from coconut shell outer fiber. It has high water retention capacity and good drainage capacity, suitable pH, good flexibility, degradable, renewable, and low price.
