NOVELTY - Cultivation of rice involves using pesticide to reduce farm pests and kill grass crops for laying farmland in rice growth; exposing farmland for 3 days under sun to fully kill pests and grass crop; tilling farmland using rotary tiller and dividing farmland ridges; applying fertilizer which comprises 1-5 pts. wt. urea, 9-13 pts. wt. boric acid, 5-7 pts. wt. potassium carbonate, 10-15 pts. wt. methylene succinic acid, 3-5 pts. wt. trace elements and 1-3 pts. wt. growth regulator; crushing straw with 1-3 cm length and mixing with plant ash, soybean cake and probiotic bacteria liquid.    USE - Method for cultivating rice (claimed).    ADVANTAGE - The method is pollution-free and eco-friendly. It reduces pests and diseases and increases rice production with high yield and quality. The rice grain is full and nutritious.    DETAILED DESCRIPTION - Cultivation of rice comprises:    (A) using pesticide to reduce farm pests and kill grass crops for laying farmland in rice growth;    (B) exposing farmland for 3 days under sun to fully kill pests and grass crop;    (C) tilling farmland using rotary tiller and dividing farmland ridges;    (D) applying fertilizer which comprises 1-5 pts. wt. urea, 9-13 pts. wt. boric acid, 5-7 pts. wt. potassium carbonate, 10-15 pts. wt. methylene succinic acid, 3-5 pts. wt. trace elements and 1-3 pts. wt. growth regulator;    (E) crushing straw with 1-3 cm length, mixing with plant ash, soybean cake and probiotic bacteria liquid, stacking 2 meters wide, 1 m high with any length of strip cone, covering with plastic sheeting, fermenting for 2-3 weeks in high-temperature to get brown or dark brown straw, crushing, sieving, adding rice production agent, organic fertilizer, calcium magnesium phosphate, pleiotropic gene, trichlorfon and sugar filter mud, mixing, drying, sieving and sprinkling to farmland;    (F) applying pesticide for second time to remove self-generated pests and weeds in early stage of rice growth;    (G) seeding manually or using machine and sowing rice evenly; and    (H) applying fertilizer continuously to provide nutritional support for rice during late growth stage.
