The village, the same period of watermelon, some farmers listed two months earlier, and some farmers delay the watermelon, or end a few small watermelon? Xiaomu City, Xiaogan District, Maochen Town, Chenwomao Village, 5 acres of watermelons planted by several farmers, last year's fruiting is very unsatisfactory, I do not know why? They asked: What method can we use to increase the rate of saplings? The phenomenon of late or small fruit set in watermelon is often occurring in different farmers in different places every year. The main reasons are: first, the selected watermelon varieties do not adapt to the local climate; second, nitrogen fertilizers are applied to the base fertilizer and topdressing fertilizer, or the total amount of fertilizer is applied. Too much; Third, the amount of basal fertilizer is too little, and the growth of melon seedlings is weak; Fourth, there is no pruning in time; the fifth is that the parts of melon are not appropriate; and the sixth is the influence of bad weather. In order to improve the fruit set rate of watermelon, increase production and improve quality, it is necessary to grasp the corresponding technology in a timely manner. First, choose the right variety. The selected watermelon varieties should be based on the local climate and soil conditions. Under the premise of high yield, high quality, and resistance, we must choose varieties with strong fruit setting, moderate or weak growth, and low sensitivity to temperature, light, fertilizer, and water. . Second, science and fertilizer control water. Basal fertilizer should be based on organic fertilizer, apply 2500-3000 kilograms per acre, with high content of ternary compound fertilizer 30-40 kilograms, another application of potassium fertilizer 10 kilograms, to avoid partial application of nitrogen fertilizer, only urea should be used to raise seedlings . The irrigation of top dressing is generally controlled one week before the opening of the female flowers. For the weak growing cucumis seedlings, nitrogen fertilizer can be applied to promote the seedlings before opening the female flowers. Each mu can also be used Hui Man Fung active liquid fertilizer 100 ml watered 50 kg spraying, to improve the fruit setting rate has a good impetus. Third, pressure vines topping heart. When the melon seedlings appeared to grow in length, they pressed the soil at the tip of the growing point of melons, but they should not be crushed at the two points before and after the fruit-setting section to prevent damage to the young fruit. Can also be in the fruiting section of female flowers after the emergence of the fruit section before leaving 5-7 leaf topping to inhibit the growth of melon vines. Fourth, do a good job of disaster management. When the flowering period encounters rainy weather, or when it encounters high temperatures and strong winds, it should do a good job in disaster management. First, under conditions of low rainfall, plastic bags may be placed on male and female flowers that are about to open immediately after rain, and artificial pollination may be performed after rain. Second, artificial pollination may be performed when there are few insects. Before the use of branch branches folded card inserted into the soil to catch melons; Fourth, when the hot weather comes, can be covered in the larvae of young larvae to prevent melon.
Intestinal localization was administered to reduce adverse effects.
Targeted site-specific release:
Two hours in gastric juice will not disintegrate or crack, dissolve within thirty minutes of disintegrating juice, providing a perfect solution for protein and peptide drugs and probiotics.
Enteric coated gelatin hollow capsule is made of gelatin and enteric coating material in gastric juice it will not collapse, but will release in the intestines as a collapse of a target product . It is often used for special packaging of drugs and health cae products which are irritating to the stomach or unstable under acid, or dissolved and effected in the intestine.
Intestinal location administration can improve the efficacy of drugs, reduce the dose and the adverse reaction, brings the convenience to patients. Moreover , it can avoid the degradation of gral protein, polypeptide or health care products and provide the best absorption sites for them.
