Problems solved by technology

These managements have high requirements on the skills and experience of the operators. If the fertilizer and water are not properly controlled according to the seedling conditions during the critical period of jointing, it is very likely to cause a reduction in production. For large-scale rice growers, the complicated operations at this stage are time-consuming and labor-intensive. The economic benefits of rice cultivation

Abstract

The invention discloses a paddy rice fertilizer capable of inhibiting ineffective tillering. The paddy rice fertilizer capable of inhibiting ineffective tillering is prepared from strigolactone, Na2SiO3*9H2O, diatomite, urea, potassium chloride, high water absorption resin, zinc sulfate, p-chlorophenoxyacetic acid soduim salt, abscisic acid, willow bark extract product, amino-oligosaccharin, and maleic hydrazide. In applications, a tillering inhibition agent is used for inhibiting tillering close at elongation stage; a plant growth inhibition agent and a silicon fertilizer are adopted to shorten the internode length of paddy rice basal parts, shorten plant height, improve lodging resistance and disease resistance; a nitrogenous fertilizer and a potash fertilizer are adopted as a floweringpromoting fertilizer and a flower protective fertilizer, to increase tillering spike rate and setting rate; yield increasing effect is obvious. The paddy rice fertilizer is capable of simplifying elongation-heading stage management, avoiding complex field drying operation, saving manpower, reducing elongation-heading stage management technology requirement, and improving economic benefit.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a rice fertilizer for suppressing ineffective tillering. Background technique [0002] Strigolactones were originally isolated from cotton root exudates and were considered stimulators of strigolactin seed germination. Another function of it is to serve as an essential chemical signal for the connection between the root circle of plants and arbuscular mycorrhizal fungi. In addition to the above functions, strigolactone or its metabolites are also used as a new type of plant Hormones can inhibit plant branching. [0003] The standard for rice jointing is that the length of the first elongated internode at the base of the stem reaches 1-2 cm (1 cm for short-stalked varieties, 2 cm for tall-stalked varieties), and when 50% of the plants in the field reach the jointing standard, it is the jointing stage. The internode elongation of rice is carried out seq...
