Embodiment 1
[0012] Embodiment one seed drought-resistant coating
[0013] Take by weighing 200g caragana or Robinia pseudoacacia seeds, according to solid content and seed weight ratio 1: 1, lanthanum nitrate (LaNO 3 ), rooting powder, aspirin, Glomus tortuosus strains, agricultural water-retaining agent, carboxymethyl chitosan, and bentonite each account for 0.5%, 0.025%, 0.0075%, 0.6%, 3%, 6%, and 89.8675%, weighed each material crushed to 500 mesh corresponding specific gravity, mixed uniformly and evenly divided into 10 equal parts, and prepared 2% by weight sodium carboxymethylcellulose solution at the same time. Then, put the seeds into the reactor, add 5-7ml of 2% by weight sodium carboxymethyl cellulose solution to soak the seeds, then add the first powder, add 3ml of liquid phase substance after 1-2 minutes, and then add the second Two parts of powder..., so after 10 times, the seed coating is completed.
[0014] Subsequently, 3ml of a prepared mixed solution of 2% by weight so...
Embodiment 2
[0016] Potted experiment in embodiment two greenhouses
[0017] In the experiment, the bare plant was used as the control, and the local loess of Beijing was used as the substrate, and the potted plant was adopted. First, dry the soil until the relative water content is 0%, put it into a 1kg pot quantitatively, then add water according to the pot weight to make it reach three water contents of 5%, 10%, and 15%, and plant the seeds to be tested at a depth of 0.5-1.0 cm, repeat 3 pots for each group, sow 15 seeds in each pot, weigh the pots every day thereafter, replenish water quantitatively, and observe the germination situation.
[0018] The simulated drought resistance experiment is a good way to test the effect of seed drought resistance coating. The present invention verifies the drought resistance efficiency of two kinds of coated seeds of Caragana caragana and Robinia pseudoacacia through the above experiments. It can be seen that the germination rate of coated seeds is ...
Embodiment 3
[0023] Field sowing experiment in embodiment three arid regions
[0024] Random block design was used to sow on-the-spot in the sunny slope, semi-sunny slope and shady slope of the Hejiagou watershed in Wuqi County, Shaanxi Province. Each treatment was sown in 10 holes, with 3 plants in each hole, and the spacing between plants and rows was 30cm×50cm. Caragana was used as the tree species to be tested. After sowing, each hole was covered with grass. Through practice tests, coated seeds and their seedlings are significantly better than uncoated seeds (see Table 3).
