“Four Seasons Green†pumpkin is a hybrid pumpkin jointly cultivated by Shaoxing Agricultural Science Institute of Zhejiang Province and Zhejiang Fengqi Agricultural Products Co., Ltd., which is characterized by early maturity, short melons, many melons, melons, green and green. Excellent, high yield and good resistance, can be planted all year round, is an ideal variety for efficient plant cultivation and summer supplementation. The key points of its cultivation techniques are as follows:
Seed treatment. The “Four Seasons Green†pumpkin seed shell is thicker. To increase the germination rate, the tip of the pumpkin seed can be gently opened by pliers and other tools before soaking. Other soaking and germination methods are the same as conventional pumpkin seeds.
Sowing seedlings. Live or nutrient seedlings can be used.
Transplanting and planting. The variety of pumpkin knots are early, so the age should not be too long, and it is better to transplant the first true leaves when they are unfolded. The planting density is about 700 plants per mu in summer, and the plant spacing is 1.5x0.6 meters. In winter, the average acre is about 900 plants, and the plant spacing is 0.5x1.5 meters. The seedlings and seedlings are transplanted. Farmers with high technical level can also use the live broadcast method of Daejeon, but pay attention to pests and rats, and at the same time properly shade.
Fertilizer management. The base fertilizer should be applied at a time before transplanting, and the organic fertilizer such as pig penn fertilizer should be applied about 1000 kg per mu, and the strips should be placed 30 cm away from the root of the melon; when transplanting, the seedlings should be well prepared according to the prescribed plant spacing. Apply 20 kg of compound fertilizer per acre of agricultural technology to the hole, and then put a small amount of soil to prevent the root of the seedling from contacting the compound fertilizer; after transplanting, use the thin human excrement to root to survive. In the future, depending on the growth of the pumpkin, the number and number of top dressings will be determined. In principle, it is “pre-foot, medium-term supplement, and post-controlâ€.
Separating fruit. The cultivar of this variety has the characteristics of short vines and many branches. Generally, it is suitable to adopt single vine pruning when planting. In the field with high fertility, double vine pruning can also be adopted. If the fruit is too early, it is not good for the growth. The higher the stall position, the faster the speed of the long melon and the larger the melon. Therefore, it is necessary to leave melon according to market demand, and the 1-1-2 stalls should be removed.
Pollination sitting melon. "Four seasons green" pumpkin has more female flowers and less male flowers. Artificial cultivation must be carried out in protected cultivation. In the case that the male flower is not enough, any other male flower of the pumpkin can be used; in the open field cultivation, other varieties with more male flowers must be planted to ensure that the pumpkin is swollen.
Pest Control. It is necessary to prevent and control diseases such as powdery mildew, viral diseases, mites, mites, leaf miners, and diamondback moth.

An active substance is the main active ingredient in a drug. Take a simple aspirin for example. Acetyl salicylic acid is synthesized through chemical process and purified to a specified purity. The synthesis of acetyl salicylic acid is made by adding various excipients, such as fillers, adhesives, disintegrating agents, etc., and then pressing it into tablets. The production of apis is generally either pure chemical synthesis, biological fermentation, or semi-synthesis, with biological fermentation followed by extraction followed by synthesis. Not all pharmaceutical enterprises make API by themselves, and many manufacturers do not have the scale to produce API. Even if there is large-scale production, the cost of production may be much higher than that of procurement. Therefore, most manufacturers buy bulk drugs, and then make preparations, so that the production of drugs can be completed without a very large scale. At present, China and India have become the two largest API producers in the world. Many European and American pharmaceutical companies, even some of their own original drugs, will give up the production of API as the patent expires and the market matures, and turn to purchase apis from China and India,API production generally go through laboratory, generated through laboratory bottle container canister, taking after successful, pilot magnification, which is to enlarge the quantity of the production, then no problem tends to be faced with a lot of small scale experiment, a very simple example, the heating process, due to the relatively small amount in the laboratory, uneven heating cases is less, But if it is scaled up to a few tons of pot, at this time the heating may be not hot in this place, where the paste pot, at this time you need to stir, but the speed of mixing is appropriate, this process needs to calculate or grope. Finally from the pilot test, and then to the formal production, the volume of further amplification, and will face a lot of new problems. Therefore, although some drugs are generic, the research and development of the whole process from small test, pilot test to the final mass production is indispensable, so even generic drugs have very high research and development costs.
