Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific examples.

[0016] Recipe 1: Complex phthalein nucleic acid 15 ppm.

[0017] Recipe 2: complex nucleic acid 20 ppm.

[0018] Recipe 3: Complex phthalein nucleic acid 50 ppm.

[0019] Recipe 4: complex phthalein nucleic acid 80 ppm.

[0020] Recipe 5: complex nucleic acid 125 ppm.

[0021] Formula 6: complex peptide nucleic acid 150ppm.

[0022] When the regulator is sprayed on the foliage: 80ppm of complex phthalein nucleic acid is used for rice seedling cultivation. The spraying time can be 1 leaf and 1 heart after planting after the seedling tray is filled with soil and 2-5 days before transplanting. Each standard machine transplanted seedling The volume of solution sprayed on the tray was 100 ml. In this application method: the concentration of complex phthalein nucleic acid used is 20ppm, 40ppm, 60ppm, 70ppm, 80ppm, 100ppm, 120ppm, 140ppm and 150ppm; the application amount is 50m...

Abstract

The invention discloses an applying method of a compound phthalic acid rice seedling regulating agent, belonging to the technical field of crop seedling regulation and control. The compound phthalic acid rice seedling regulating agent is characterized by containing compound phthalic acid with the concentration of 15-150ppm; during the growth period of rice seedlings, the compound phthalic acid rice seedling regulating agent is sprayed twice, respectively in a one-leaf one-core period and in 3-5 days before transplanting. The compound phthalic acid rice seedling regulating agent is capable of remarkably promoting the reviving growth and early tillering of mechanically transplanted rice seedlings and remarkably increasing absolute plants, thereby remarkably increasing the rice yield; during applying, the compound phthalic acid rice seedling regulating agent is applied on leaves, and is simple to use; and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of crop seedling regulation, and specifically relates to a compound phthalate nucleic acid rice seedling regulating agent 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 damaged during ma...
