Problems solved by technology

[0002] In some places, double-cropping rice is cultivated. Due to the low accumulated temperature, the early rice seedlings need to be planted in early May, and the early rice seedlings should be sown from early March to late April. However, in some areas, such as Guilin and Hunan, the temperature is low and

Embodiment

[0017] A cold-proofing agent for early rice seedlings is a solution mixed with the following raw materials in parts by weight:

[0018] Glucose 35

[0019] Allantoin 25

[0020] aspirin 8

[0021] Gibberellin 0.4

[0022] 500 for water.

[0023] The usage method of this antifreeze agent is:

[0024] 4. For seed soaking, before rice germination and sowing, dilute 10 times with this product, shower or soak grain buds for 1-2 minutes;

[0025] 5. 5 days after sowing, drain the water, dilute 5 times with this product, and spray on the leaves;

[0026] 6. Spray again before transplanting.

[0027] Such use can not only improve the cold resistance of the seedlings and prevent rotten seedlings, but also increase the white roots of the seedlings and make the seedlings strong.

Abstract

The invention discloses an early rice seedling cold-proof agent and a using method thereof. The early rice seedling cold-proof agent is a solution formed by mixing, by weight, 30-40 parts of glucose, 20-30 parts of allantoin, 6-10 parts of aspirin, 0.3-0.5 part of gibberellin and 500 parts of water. The early rice seedling cold-proof agent has the advantages that the concentration of cell sap can be improved through the glucose, the cold hardiness of the cells can be improved through the allantoin, the aspirin has the antibacterial function, and the gibberellin has the growth stimulation function. After scientific compatibility of medicines, the cold resistance capacity of early rice seedlings can be improved, and the seedlings can be better promoted to grow strong.

Description

technical field [0001] The invention relates to early rice seedlings, in particular to an anti-cold agent for early rice seedlings and a use method thereof. Background technique [0002] In some places, double-cropping rice is cultivated. Due to the low accumulated temperature, the early rice seedlings need to be planted in early May, and the early rice seedlings should be sown from early March to late April. However, in some areas, such as Guilin and Hunan, the temperature is low and Lack of sunshine often causes early rice seedlings to rot, affects the transplanting of early rice, and even affects the cultivation season of late rice. At present, the cold protection method adopted is to use nylon film or cold tail and warm head sowing, but the phenomenon of rotten seedlings still occurs. Contents of the invention [0003] The object of the invention is an anti-cold agent for early rice seedlings and its application method, which can improve the ability of the seedlings t...
