During organic rice cultivation, the requirements for organic production must be met in terms of seed treatment, seedling bed treatment, field management and pest and grass control. Specifically, organic rice is grown in the following ways。
I. Selection of good quality and emphasis on excellent words. Seeds of organic rice are selected to be resilient (mainly resistant to pests), highly divided, big ears, nutritious, commercial, high-quality rice, varieties suitable for dry seedlings and super-scarce cultivation models, with a gestation rate of more than 95 per cent and a purity and purity of more than 99 per cent, and cannot be cultivated beyond the limits, ensuring full maturity in the first five to seven days of the frost, a proper mix of early and evenings, and the full use of the seeds' “sown and land for all”. Seed treatment prior to seeding to ensure a single seeding to preserve seedlings。
2. Early arrest and early broadcast in due course. When temperatures are stabilized at 5°c, seedlings can be planted at 1 to 2 concentrations of temperate zones, at the beginning of april, 3 to 4 clusters of temperate zones, at the end of april, at the end of april, after planting, at the end of may, and at large sheds of dry or smouldered seedlings, with every effort to grow strong. When the temperature stabilizes at 13°c, it begins to insert, using ultra-remote plugs, without the june plugs, to improve the quality of the plugs so that they can rise up, drop in, drop in, fit in, fit in, fit in, fit out, and be reasonably concentrated, and to detect the loss of seedlings in areas where they are not available, carry out seedling replanting and ensure that the whole seedling is fully bred。
3. Reasonable fertilization and guaranteed supply. Organic rice can be applied only to organic fertilizers, preferably in the form of cakes, chicken dung (but must be decomposed, fermented) etc. It must never be applied to fertilizer, it must be applied in a sufficient quantity, 300 kg of fermented chicken dung per acre, it must be applied evenly, it cannot accumulate in order to avoid the burning of seedlings, it must be followed with less food, it must be followed mainly by high-quality farmers, it must preferably be followed up with pie fat, it must be applied in accordance with the strength, strength and bottom, it must be properly followed up, and it must primarily be matched by the need for nutrients to provide for the fertilizing, fertilizing, wiping, wiping and fertilating of rice。
Iv. Clean water irrigation, scientific water use. Organic rice must be irrigated with clean water, must not be used for domestic sewage, industrially used for water irrigation, should be ploughed on a single line of water, managed on a shallow basis, warmed by water, driven by water, so as to feed its roots, protect its leaves and mature. Specific methods of water irrigation are: shifting flowers to water during the planting period, returning 2 to 3 cm of water layer, before the effective separation of the water into shallows, increasing the temperature of the ground and water, promoting partitions, at the end of the effective partition, immediately draining the tan fields from the areas where they are growing, 7 to 10 days of control of the ineffectual fractions, tans to the level of whiteness of the fields, cracks on the ground, white surfaces of the ponds, and absity of the leaves, which promote the growth of the roots. After draining the field, dry, wet and dry intermittent irrigation is carried out in order to protect the leaves and protect the roots. In the later stages, deep-water tires, approximately 15 centimetres of water, are used as an effective defence against barrier-type cold temperatures. Yellow season shut down。
V. Integrated response to the disaster and the harvest. Organic rice does not use chemical pesticides for weeding and pest control, artificial weeding, defusing soil, improved permeability, clean-up of soil, promotion of root system development, prevention of pests and diseases, mainly biological and physical measures such as rice field ducks, preparation of predictions, and immediate prevention if they occur。
