Four Key Points of Rice Seedling Cultivation Technology and Materials Needed for the Seedling Soil Formula
Rice is now our most important food, it is our staple food, so how much do you know about rice cultivation methods? Let's first take a look at the rice seedling cultivation methods below! Seedling cultivation methods 1. Seedbed soil Use one part wood shaving compost (each box weighs about 520 grams, 125 kg per hectare), add one part crushed rice husk (each box weighs about 150 grams, 36 kg per hectare), add one part soil (each box weighs about 800 grams, 192 kg per hectare), that is, a 1:1:1 volume ratio as the seedling cultivation material. The mixing method is carried out with a mixing mixer, or one part wood shaving compost and one part crushed rice husk are evenly spread on the upper layer of the soil pile, then mixed into the soil with a tractor, and finally screened with an electric soil crushing and soil sieving dual-purpose machine to obtain uniform seedbed soil. For covering soil, mix one part crushed rice husk with one part soil (that is, 1:1) for covering. The total soil amount including covering soil, calculated at 300 grams per box, is 264 kg per hectare. Compared with the current 432 kg of seedling soil mixed with rice husk and soil, this saves 168 kg per hectare (38.9%).
