Planting method of non-toxic rice

Abstract

The invention provides a planting method for non-toxic rice, and belongs to the technical field of agriculture. The planting method comprises the following steps of preparing a base fertilizer, preparing a paddy field, carrying out paddy field arrangement, planting the rice, and carrying out normal field management, and also comprises the following steps of carrying out pretreatment on the paddy field, carrying out sowing, carrying out field management before seedling pulling, transplanting rice seedlings, carrying out field management in the growth period, carrying out treatment before harvest, and carrying out harvesting. According to the method, a traditional Chinese medicine is used for sterilization and deinsectization, so that the effects of sterilization and deinsectization are achieved under the condition that no chemical pesticides are used, meanwhile, a greenhouse and a temperature control and water control system are used for carrying out controlled planting on the rice in the paddy field, so that the interference of outdoor plant diseases and insect pests to the rice is isolated, meanwhile, the growth environment of the rice can be improved and automatically controlled,the yield of the rice is increased, in addition, a base fertilizer body and traditional Chinese medicine residues are adopted as the base fertilizer, so that soil is improved, salinization of the soil is avoided, and the traditional Chinese medicine residues can be further used as a fertilizer to promote the growth of the rice when being rotted and decomposed.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for planting non-toxic rice. Background technique [0002] Rice likes high temperature, high humidity, and short days, and it does not have strict soil requirements, and paddy soil is the best. The minimum temperature for seedling germination is 10-12°C, and the optimum temperature is 28-32°C. The daily average temperature of tillering stage is above 20℃, and the optimum temperature for ear differentiation is about 30℃; low temperature prolongs the differentiation of branches and spikelets. The optimum temperature for heading is 25 to 35 °C. The optimum temperature for flowering is around 30°C. If it is lower than 20°C or higher than 40°C, fertilization will be seriously affected. Relative humidity of 50 to 90% is appropriate. However, in real life, rice is grown outdoors, and the temperature depends on the weather. Because of the weather, it is easy to cause rot...

AI Technical Summary

Problems solved by technology

However, in real life, rice is planted outdoors, and the temperature depends on the weather. Because of the weather, it is easy to cause rotten seedlings, dead seedlings or burns of seedlings.

[0003] At present, there is a bottleneck that the survival rate of transplanted rice seedlings cannot be further improved. Improper cultivation methods restrict the increase of rice yield; Rotten buds, as well as the occurrence of various diseases and insect pests of rice, have caused a significant reduction in rice yield, affecting the normal income of farmers, and during the period of rice planting, farmers need to go to the field for management, which is time-consuming and labor-intensive. For example, the application publication number is The high-yield planting method of rice disclosed in CN105210650A, although the nutritional value of rice has been improved, can not solve the problems of damaged seedlings and rotten roots during the growth of seedlings.

[0004] In addition, there are many diseases and insect pests in rice, and chemical pesticides need to be applied frequently to ensure a high yield, but the residues of pesticides are very harmful to the human body. Eating rice with too many pesticide residues for a long time can easily lead to various diseases, and pesticides will also follow. Erosion damages the environment or salinizes the soil
