Rice mechanical transplanted plate seedling raising and rooting agent and application methods thereof

Abstract

The invention relates to a rice mechanical transplanted plate seedling raising and rooting agent and an application method thereof, belonging to the technical field of the rooting agents of crop seedlings. The rice mechanical transplanted plate seedling raising and rooting agent is characterized by containing an auxin type plant growth regulator and sodium dichloroisocyanurate, wherein the concentration of the auxin type plant growth regulator is 1-10ppm, and the concentration of the sodium dichloroisocyanurate is 50-200ppm. The rooting agent contains the auxin type plant growth regulator andthe sodium dichloroisocyanurate, and can significantly promote green-turning and growth of mechanical transplanted seedlings, promote early occurrence of tillering, significantly increase effective panicles and further significantly increase the rice yield. The rooting agent adopts two application methods, namely seed soaking application and fertilizer spraying application, the use is simple, andthe operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of root plasticizers for crop seedlings, and specifically relates to a plastic root agent for rice machine-inserted seedling raising and an application method thereof. Background technique [0002] Rice machine transplanting uses plastic trays for seedling cultivation. The commonly used plastic tray specifications are 58cm in length, 28cm in width and 2cm in height. Generally, 80-100g of buds are sown per tray for hybrid rice, and 120-150g for conventional rice. The rice root system grows in a coiled state at the bottom of the seedling tray, and many roots are intertwined to form a white root blanket at the bottom of the seedling tray. These roots are coiled in the soil with a thickness of only 2-2.5 cm, and the rhizosphere is very crowded. , resulting in a reduction in the number of root hairs, resulting in a reduction in the quality of the seedlings raised in the tray. The root system is broken and damage...

Problems solved by technology

[0003] The following methods are mainly used to improve the root damage of machine-transplanted rice seedlings: ①In production, various fertilization methods and root growth promoters are mainly used to promote the growth of rice roots, in order to reduce the damage of machine-transplanted roots. More roots will cause more damage to the seedlings during machine transplanting; ②Some rice farmers use to cut off the excessive roots at the bottom of the seedling tray before machine transplanting, so as to reduce the damage caused by the sampler pulling too many roots at the bottom during machine transplanting. Damage the root system of the upper part, but this method is only suitable for small-scale farmers, and it is labor-intensive and time-consuming; ③The transformation of the seedling tray is another method, such as the bowl-shaped blanket-shaped seedling tray, which is transformed from the seedling-raised tray structure, implement the seedling raising method of upper blanket and lower pot, and cooperate with the improvement of machine transplanting technology, which can improve precision seeding and seedling raising, especially for the cultivation of hybrid rice machine transplanting seedlings to a certain extent

However, the pot-shaped blanket-shaped seedling tray increases the cost of the seedling tray, and the technical requirements for machine-transplanted bowl-shaped blanket-shaped seedlings are relatively high. If the sampler cannot accurately pick up the seedling pot, it will be the same as the traditional tray. Therefore, this project It is difficult to promote the technology in a large area in my country, especially in the southern rice areas
