1. The varieties with short growth period and the long growth period are matched with other varieties such as taro, big melon, western celery, wintering sweet-blue, carrot and so on. The growth period is longer and it is possible to interplant the short-lived, medium-sized leeks in the early growth period. Cabbage, leeks, kale, spinach, early maturing cucumbers, ripening melons, radishes, etc.
2. Hi-light varieties and shade-tolerant varieties with, such as cowpea + cabbage gap three-dimensional planting.
3. High pole variety and short pole variety, upright type and climbing type. Such as onion + spinach (or cabbage), onion + Ganlan.
4. Deep-rooted varieties are paired with shallow-rooted varieties. For example, deep-rooted late fruit vegetables such as gourd, wax gourd, eggplant, etc., and shallow-rooted green leafy vegetables such as Chinese cabbage, Chinese wolfberry, leeks, etc. are composed of multiple layers and interplanting.
5. Arrange a reasonable field population structure, such as melon + tomato three-dimensional cultivation, can be introduced to the tomato melon vine climbing growth, not only the use of frame materials, and the late tomato fruit due to the appropriate shade of winter melon, It also reduces the sunburn of the fruit.
6. Early celery seedlings under melon sheds, such as melon (or sponge gourd, gourd gourd, etc.) cultivated in Daping, grow to late July to August, and sow early celery seedlings on pods without melons.
7. The use of vertical temperature differences between high-altitude mountainous regions and plains, such as the anti-seasonal growth in areas above 800 m above sea level in summer and the out-of-season production of greenhouse facilities in winter and spring plains.
8. Cultivation technology of indoor stand facilities, such as the stand to grow water spinach vegetables, lettuce, Chinese cabbage, Chinese wolfberry, leeks, etc., spread green leafy vegetables, make full use of space, factory production of vegetables, but to lighting, heating and air conditioning and other facilities.
Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing key intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
