Abstract:

To systematically study the techniques of light medium seedlings of Toxicodendron succedaneum, taking the seed of Toxicodendron succedaneum in Jiangxi for the materials, seedlings were planted in the light matrix of water control test. Water control test set a total of three different treatment intervals of watering of 1 day, 3 and 5 days, respectively measurements growth indicators twice in the 15th day and 30th days to study about intervals of watering light matrix system of Toxicodendron succedaneum seeds breeding on seedlings height, diameter and length of compound leaves. The results showed that: the comparison of different treatment intervals in the water, the Toxicodendron succedaneum seed breeding on seedlings height, diameter and length of compound leaves had shown significant differences. Seedling height growth of seedlings under conditions of controlled in the water, the initial impact of water in a controlled manner would be affect to the seedlings in the latter part of the growth rate of height; wet and dry harmony was beneficial for the control growth path to ground water, but excessive control of the water in diameter growth was not obvious; nursery early, compound leaf length in the case of water control rapid growth, once a day of the watering treatment for the negative growth; nursery late, plenty of moisture was conducive to metabolism and more conducive to the growth of leaves. Early control of water, measures of moisture adequate later for the leaf growth was beneficial and appropriate control the water more conducive than the over-control water was to the growth of leaves. Therefore, an interval of 3 days of water treatment for seedling height, diameter, and length of growing compound leaf was the most favorable, which provided a guided theory for people in watering at the seedling stage and late planting.
