In recent years, due to the heat of ecological farms, more and more tomatoes have been planted. Tomatoes grown on ecological farms require high yield and high quality, that is, not only high yield, but also good taste, and full tomato seeds. Then, if you want tomatoes to achieve high quality and high yield, you should work hard on planting techniques. The following small series will introduce the cultivation technology management of high-yield and high-quality tomatoes.
1. Water and fertilizer management during tomato coloring
The water and fertilizer management of the tomato coloring period can not be large and fat, but the watering frequency is reduced as much as possible. The soil is kept dry and wet, and it can be properly drought. The best standard is that the tomato plants show one at one or two in the afternoon. A little bit of wilting symptoms, and in the evening can return to normal, through this method can make tomatoes reach the accumulation of sand and sugar.
Second, temperature control
For tomato planting, the temperature should not exceed 15 °C at night, and the minimum temperature should not be lower than 10 °C. The purpose is to make the nutrients produced during the day turn to reproductive growth as much as possible, and provide it to the tomato fruit, and the other is to increase the temperature difference between day and night. Conducive to the accumulation of tomato sugar.
Fourth, remove the first flower of each flower
Because the first flower of each flower of tomato is opened earlier, if the first flower is not removed, the fruit of this flower will affect the nutrient supply of other flowers, so it should be removed in time.
5. Choose flowers with close opening time and better flower shape for flowering
The stems of the tomatoes are opened in order from top to bottom. In sunny weather, most of the flowers can be opened at the same time or only one day apart. On the day when the flower is open, choose a flower-shaped flower, a corolla, and a long flower head. In this way, the difference between the two days is enough to determine the flower that meets the requirements of a flower. The flowers that are open after the flower spikes should be removed in time, without going to the flowers.
6. The deformed fruit on the tomato ear should be removed in time.
The standard ear of tomato generally leaves 4-5 fruits that meet the quality of the production. The above deformed fruit and excessive fruit should be removed in time to avoid excessive consumption of nutrients and cause fruit malnutrition.
Seven, tomato fruit expansion period should be sufficient
After the pollination of the tomato, the fruit generally enters the fruit expansion period for about 10 days. The tomato needs to ensure sufficient water and fertilizer supply. When the weather conditions permit, timely watering and fertilizing according to soil moisture. After the tomato enters the fruit-expanding period, do not use the potassium nitrate-containing component to fertilize the fertilizer, and use the potassium sulfate-containing fertilizer to enhance the taste of the tomato.
Finally, it is necessary to maintain a relatively high temperature during the fruit expansion period of the tomato, which can also promote the tomato's taste better. Has the planting technology of high-yield and high-quality tomatoes been known?
The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
