The invention discloses a special weeding method for paddy rice and upland rice by direct seeding. The special weeding method comprises the following steps: (1) sealing soil: adding 250ml of 60% butachlor, 400ml of 48% butralin, 50g of 50% quinclorac, 50g of 2-methyl-4-chloro-phenoxyacetic acid sodium and 100ml of 33% stomp prowl into each 667M<2>; mixing and adding 75kg of water and agitating uniformly; after seeding for 7-10 days, spraying field soil; (2) treating stems and leaves: mixing 250ml of the 60% butachlor, 25g of the 50% quinclorac and 50ml of Basagran into each 667M<2>; mixing and adding 40kg of the water; agitating uniformly; and spraying weeds in sunny days when barnyard grass has two leaves. With the adoption of a formula of a novel special herbicide for the paddy rice and the upland rice, which is directly sown by the method, the preventing and removing effects of weeds concomitant with the upland rice are up to more than 95% and the field weed dangers are basically eliminated; the selectivity is strong and the inhibition and phytotoxicity are not caused on the growth of rice plants after the medicine is applied; and sprouted seedlings are ordered and the fertility is normal.

It is intended to provide a phytotoxicity controlling agent usable as a herbicide for upland farming, which exerts a sufficient herbicidal effect on weeds growing together with upland crops, for example, wheat, rye, barley, oat, corn, sorghum, cotton, soybean, adzuki bean, oilseed rape, beet, upland rice and so on but causes no phytotoxic phenomenon (for example, growth inhibition, growth suppression, tiller inhibition or yellowing) in cultivated plants, comprising a nuclear-substituted benzoic acid represented by the following general formula:wherein R1 represents linear or branched C4-15 alkyl; a salt thereof or an alkyl ester thereof.

The invention discloses a method for planting upland rice with both water and dry uses, comprising: (1) hybrid breeding, using conventional rice as the female parent and wild rice as the male parent to perform repeated hybridization to obtain optimized seeds; (2) soil treatment, Including improving the soil and disinfecting and killing insects; (3) seed soaking treatment, soaking the seeds in salt water and hot water for 20‑30 hours after drying for 6 to 8 hours; (4) sowing, using field transplanting seedling raising method, on-demand Sow the seeds in the field or dry land by any method in the direct seeding method or the direct seeding method; (5) irrigation management, soak the ground with water once every 5-7 days, until the seedlings are on the tire, heading, and seeding, and continue to keep the soil moist; (6) Prevention and control of diseases and insect pests, adopt targeted methods in different control periods. The planting method of the invention has higher yield and wider adaptability, and is not only applicable to field planting but also dry land planting.

The invention relates to mountainous upland rice and a planting method thereof. The planting method comprises the following steps of land selection and preparation: selecting a land with sunny exposure and good leeward as a planting land, turning soil and ploughing deeply, compartment construction and fertilizer application: constructing compartments on the planting land, setting a fertilizer groove between every two compartments, and then applying fertilizer in the fertilizer grooves, ridging and film covering: ridging on the fertilizer grooves and then covering films on ridge surfaces, seeding: punching and seeding at a fixed distance on the ridge surfaces covered with the films, and when the daily average temperature is above 8-10 DEG C for three days continuously, sowing the upland rice, and then, field management. The mountainous upland rice planting method is especially suitable for upland rice microfilm covering thermal insulation cultivation in a mountainous area which is 1000-2500 meters above sea level, and effectively breaks the history of no upland rice planting in the mountainous area which is more than 1000 meters above the sea level; the advantage is fully used that the temperature difference between day and night is large, and therefore the organic matter accumulation for kernel crops such as starch is facilitated, and finally, paddy which is high in rice rate, good in rice quality, organic and green, and good in quality is obtained.

The invention discloses a plant drought resistance related protein OsERF62, its coding gene and application thereof. The protein provided by the invention is derived from upland rice, is named as OsERF62, and is composed of the amino acid sequences shown as sequence 1 in the sequence table. Experiments prove that, the recombinant expression vector 35S::OsERF62 containing a DNA molecule (i.e., the coding gene of the protein) shown as the 102nd-1106th position of sequence 2 in the sequence table is employed to transform paddy rice Nipponbare to obtain OsERF62 gene overexpressed T2 generation transgenic lines, and under the following 3 drought stress treatment, i.e. 200g / L PEG6000, 200mmol / L mannitol and soil water cut-off, the survival rates or growth vigor of the plants are both significantly higher than those of the wild type paddy rice Nipponbare. The invention provides a new gene and method for improving plant drought tolerance, thus having important significance in plant genetic improvement and drought tolerance study.
