and (4) test conclusion:
1. suitable ammonium nitrate ratio (NH)4 +:NO3 -10: 90) can improve the growth and development of the small Chinese cabbage seedlings under weak light. Under weak light, compared with full nitrate nitrogen treatment, the addition of ammonium nitrogen with proper concentration in the nutrient solution can promote the development of lateral roots, improve the configuration of the root system, increase the absorption area of the root system and facilitate the plants to absorb water and nutrient substances; on the other hand, the stacking degree of chloroplast basal granule sheet layers can be increased, the integrity of chloroplast structures is protected, the photosynthesis of plants is improved, and the growth and development of the plants are further improved.
2. The anti-oxidation mechanism suitable for relieving the weak light stress of the small Chinese cabbage seedlings by the ammonium nitrate ratio is as follows: under weak light, the proper ammonium nitrate proportion can improve the activity of antioxidase of small Chinese cabbage seedlings, improve the capability of removing lipid peroxidation substances of plants and reduce the damage to the plants caused by adverse circumstances.
4. Meanwhile, the damage of weak light to the small Chinese cabbage seedlings can be relieved by introducing nitric oxide into the culture solution, however, the effect of the ammonium nitrate nutrition on the reduction of the small Chinese cabbage seedling growth under the weak light is obviously reduced by adding a nitric oxide inhibitor (L-NAME and NaN 3) and a scavenger (Hb) into the proper ammonium nitrate nutrition, and therefore the regulation effect of NO participating in the ammonium nitrate nutrition on the small Chinese cabbage seedling growth under the weak light is proved.
