Abstract

Etant donné que la cellulose (en particulier, la cellulose cristalline), qui est communément utilisée en tant que charges dans des préparations, possède un effet stimulant la croissance végétale, des compositions contenant de la cellulose avec au moins un composant sélectionné parmi le gel de silice, la terre à diatomées, l'alun, le carbonate de calcium, le bioxyde de calcium et le glucose sont utiles en tant que promoteurs de croissance végétale. Le riz non décortiqué, le sucre de betterave, la tourbe, le melon, et ainsi de suite, revêtus des compositions de revêtement pour semence contenant les compositions de promoteur de croissance végétale ci-dessus présentent non seulement un taux de germination élevé, mais aussi une croissance favorable. Dans les céréales, telles que le riz, et les légumes-racines, tels que la betterave, on peut s'attendre à une augmentation du rendement. Le revêtement de semences de riz désinfecté au moyen des compositions de revêtement pour semence contient la composition de promoteur de croissance végétale ci-dessus, le prétrempage et le trempage des semences pouvant être omis au cours du prétraitement (sélection par gravité spécifique, désinfection, prétrempage et trempage). Ainsi, de la main-d'oeuvre peut être économisée dans la croissance de semis de riz. En outre, aucune liqueur résiduaire contenant les agents de désinfection libérés des semences désinfectées n'est formée au cours du- prétrempage, ce qui représente un avantage écologique.
