First of all, the walnut trees that have been set up are applied after flowering. The amount of urea applied is 250 g and 150 g of compound fertilizer (high phosphorus content); the newly planted and tested fruit of walnut trees is 15 cm long at the new shoot. Into the amount of 100 grams of urea plus 50 grams of compound fertilizer. Secondly, foliar spray fertilizer, spraying gibberellic acid and boron fertilizer at the peak of female flowers can increase the fruit setting rate. Spraying 0.3% to 0.5% urea every 15 days can quickly increase the strength of the blade and increase the thickness of the leaves. Top dressing and foliar spray can be performed simultaneously or alternately.

After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
