A large crop of long eggplants in Jitai Town, Shouguang City has begun to plant at the end of July and early August. Many vegetable farmers have reported that under the current temperature environment, the eggplant seedlings after the slow seedling are easy to grow and grow, which is not conducive to Cultivate strong trees in the early stage, and because the big crop is pulled out in June of the second year, the growing period is as long as 10 months. If the early management is not good, it will be difficult to achieve high yield in the later stage. In this regard, it is recommended to focus on two points in the management of vegetable farmers to prevent fleeing:
Promote the next: water control, squatting and hoeing frequently
The slow seedling water after eggplant planting should be determined according to the soil moisture. Normally, the slow seedling water should be poured in 5-7 days after the eggplant is planted. The amount of water should flow to the front end of the planting row. After pouring the slow seedling water, the seedlings leave two branches of uniform size, and then control the water to squat the seedlings (if the soil moisture in the shed is low, water small water appropriately), when the doorjapan sits and grows to about 5 cm, Water the ridges after supporting the ridges to promote the rooting down.
Shoveling can not only increase the permeability of the soil, but also is a good measure to promote rooting. However, since the seedlings are still relatively small after the slow seedling, it is reminded that the vegetable grower must be careful during the first stroke. Swipe lightly to prevent the taproot from being cut off. Afterwards, the hoe can be cut appropriately, generally with a depth of 5-6 cm, which can cut part of the root system, which can play a role in squatting the seedlings and also achieve the purpose of promoting roots and growing strong trees.
Control: take multiple measures and take precautions
Although the temperature has dropped slightly in the morning and evening in the past few days, the temperature is still high during the day, especially around noon. The "Autumn Tiger" has not yet passed, and the control of prosperity should not be underestimated. After the plant has set fruit, in order to ensure the balance between vegetative growth and reproductive growth, when the first eggplant to be left has grown to half the size of the finished fruit, the excess side branches can be removed, which can promote the reproductive growth of the plant, and it can also Avoid prosperous plants.
In addition, it should be noted that too high night temperature is also an important reason for the growth of trees. It is recommended that vegetable growers should increase ventilation in the management of the shed, spray water on the leaves, control the number of watering and other measures to reduce the shed temperature and restrain Prosperous.
If the tree is still growing after the above physical control measures, it can be adjusted by using plant growth regulators, such as mepiquat, paclobutrazol, etc., but the concentration of the drug must be used carefully to avoid excessive concentration or too low concentration Unable to control the tree, thus affecting the normal growth of the plant.

3. Application
Printing and dyeing industry: mainly used for dyeing vat dyes suspension, leuco acid staining, dispersion and soluble vat dyes dyeing. Also be used for silk / wool interwoven fabric dyeing, the yarn is no color. Mainly used for industrial dye dispersion and diffusion of color lakes manufacturing additives.
Building materials industry: as early strength cement water reducing agent, the amount of 0.5-1% by cement after the shock has good dispersion effect, increasing the strength of cement. Diffused N of concrete tensile strength, impermeability, frost and compressive modulus of elasticity are improved, no corrosion of steel effect.
Pesticide industry: It can be widely used in wettable pesticides, with good dispersion and solubilization, can significantly improve the efficacy, dosage according to product requirements. Example: buprofezin, the amount of 3-5 %; thiophanate amount of 0.8-1.5 %, 0.8-1 % Kai Ling vegetables.
Electroplating industry: the color is added, crossing pigment dispersants N allows uniform dispersion can significantly improve the plating surface brightness, and the amount is usually 10% of the pigment.
Rubber industry: rubber (latex) of industrial production process, the dispersed substances such as sulfur accelerator, antioxidant zinc oxide fillers ( such as barium sulfate , calcium carbonate ), etc., added to the dry weight of a dispersing agent N2-4% , 10% dispersant solution prepared in advance , and along with the other components in a ball mill grinding , can improve the dispersion effect and shorten the milling time .
Packing: 25kg bags.
Storage: two years and must be upload and download lightly.
