An objective of the present invention is to provide gibberellin-binding proteins, genes encoding such proteins, and applications therefor. The proteins of the present invention function as cytoplasmic receptors for gibberellin and mediate gibberellin response in plants. Plants overexpressing such genes exhibited gibberellin-hypersensitive phenotypes, such as increased plant height. In contrast, plants in which the genes were mutated exhibited gibberellin-insensitive phenotypes, and thus became dwarfed. Accordingly, plant differentiation and growth can be regulated by introducing the gibberellin-binding genes of the present invention or by suppressing the expression of same.

The invention relates to a paddy rice direct seeding method with weeding and lodging-resistant functions, and belongs to the technical field of agricultural cultivation. The paddy direct seeding method comprises the following steps that 1, it is kept that ditch surfaces of a field is free of water, and paddy direct weeding is carried out; 2, when one leaf and one core grow on each paddy seedling,field water irrigation is carried out; 3, when 3.5-5 leaves grow on each paddy seedling, field water is drained, a weeding agent is applied, and 2-3 days later, field water irrigation is carried out;4, when the number of productive ear in every 667 m<2> of colony reaches 80% or the number of seedlings reaches 120,000, field drying is carried out till field soil cracks, and field water irrigationis carried out again when white paddy roots appear on the field surface. The method can effectively prevent and remove weeds, reduce the consumption of the weeding agent, reduce direct-seeding paddy lodging and effectively improve the stable yield of direct-seeding paddy and the quality of rice.

The invention belongs to the field of garden plant cultivation, and more specifically relates to a garden plant growth retardant. Each liter growth retardant contains 200 mg of paclobutrazol, 20 mg of polysorbate, 10 mg of prohexadione calcium, 30 mg of vitamin, 5 mg of rhizoma arisaematis leaves juice, and 10 mg of tetrasodium iminodisuccinate. Under prerequisite that the landscape effect is guaranteed, the garden growth delaying speed is realized by the plant growth retardant, and the maintenance cost can be saved.

The invention discloses a novel nitrogen fertilizer, which is granular or powdery. The nitrogen fertilizer is characterized in that every 100 parts of the nitrogen fertilizer includes the following raw materials by mass: 6-15 parts of the amide nitrogen, 12-19 parts of ammonium nitrogen, 0.2-1 part of zinc in terms of zinc oxide, 0.5-2 parts of magnesium in terms of magnesium oxide, 0.2-1 part of boron in terms of boron oxide, and 5-15 parts of a sustained release filling material. The nitrogen fertilizer of the invention has the advantages of more reasonable raw material resource allocation, more comprehensive efficacy, lower cost, less loss and waste, environmental protection and energy saving, fills the nitrogen fertilizer vacancy, enriches existing nitrogen fertilizer variety, and provides a more forceful guarantee for agricultural development.

The invention discloses a microbial preparation for promoting rooting and lodging resistance of rice and application thereof. The microbial preparation is prepared from glucose, glutamic acid, monocalcium phosphate, sodium borate, zinc sulfate, magnesium sulfate, sodium silicate, compound probiotics and clear water. The raw materials comprise the following components in parts by weight: 50-70 parts of glucose, 2-8 parts of glutamic acid, 20-40 parts of monocalcium phosphate, 2-7 parts of sodium borate, 5-15 parts of zinc sulfate, 2-8 parts of magnesium sulfate, 2-8 parts of sodium silicate, 80-100 parts of compound probiotics and 800-1000 parts of clear water.
