Embodiment 1

[0036] The formula of the potato seed dressing agent of the present embodiment is: carbendazim powder: 250 g; bentonite: 50 g.

[0037] The preparation method of the potato seed dressing agent of the present invention is: take 50g of bentonite, grind it into a 200-mesh fine powder, add 250g of carbendazim powder, stir in a sealed powder mixer, and mix evenly to obtain the present invention. Potato seed dressing.

[0038] The method of using the potato seed dressing agent of the present invention is as follows: according to the ratio of 100:0.3 (w / w) of potato seed potato dicing and potato seed dressing agent, a certain amount of potato seed dressing agent is weighed, and the potato Sprinkle the seed dressing agent directly on the cut potato pieces, stir them evenly with a wooden shovel, so that the potato seed dressing agent evenly adheres to the cut potato pieces, cut the pieces now and mix the seeds, and then sow immediately after mixing . Wear a mask when mixing seeds, we...

Embodiment 2

[0040] The formula of the potato seed dressing agent in this embodiment is: mancozeb powder: 500g; bentonite: 100g.

[0041] The preparation method of the potato seed dressing agent of the present embodiment is identical with embodiment 1.

[0042] The difference between the using method of the potato seed dressing agent of the present embodiment and embodiment 1 is: when the potato seed dressing agent in the present embodiment is in use, the weight ratio of the potato seed dressing to the potato seed dressing agent is 1000:2.5 , and the rest are the same.

Abstract

The invention provides a potato-seed dressing agent which comprises the following effective components: the mixture of carbendazim and mancozeb, carbendazim, mancozeb or metalaxyl mancozeb. The invention further provides a preparation method and application of the potato-seed dressing agent. Due to the application of the potato-seed dressing agent, the healing of the wound of the cut potato seed block is promoted, the bacterial infection of the cut potato seed block can be inhibited, the propagation possibility of the bacteria among the cut potato seed blocks can be reduced, the loss of water in the cut potato seed block can be decreased, the rate of emergence of the potatoes can be increased, the condition that the potato seedlings are weak is improved, the occurrence of the late blight to the potatoes can be prevented effectively, and the yield of the potatoes per unit area can be increased hereby.

Description

technical field [0001] The invention relates to a potato seed dressing agent. Background technique [0002] Potatoes are one of the main crops in Gansu, especially in arid and semi-arid areas. Some varieties have problems such as low seedling emergence rate, weak plant growth and serious diseases in the late growth period, especially late blight, especially in semi-arid areas. The lack of seedlings and ridge cutting in the area is a prominent problem, which affects the yield of potatoes. Contents of the invention [0003] The technical problem to be solved in the present invention is to overcome the existing defects, and a kind of potato seed dressing agent is provided. After applying the potato seed dressing agent of the present invention, the emergence rate of potatoes has been improved, the weak condition of plant growth and seedlings has been improved, and effective The occurrence of late blight was prevented. Therefore, the present invention also provides the prepar...
