First, there should be more flowers on each flower spike. Generally, when 4~5 high-quality fruits are left on each ear, 8~9 flowers must be ordered. When the diameter of young fruit is as long as 1 cm, choose 4~5 fruits with similar appearance and size, and remove the larger fruit, deformed fruit, residual fruit and fruit with pests. And timely spraying ecological plant cell immune factors to enhance plant stress resistance, can make viral DNA break and apoptosis. Strong immune function, induce interferon and active interleukin, inhibit residual virus replication, and promote positive energy ecological growth of plants. Control the plant physiological diseases and invasive diseases by the host plant resistance mechanism and the principle of pathogenic toxicity variation.
Second, remove the first flower, the first flower or the first and second fruits on the flower spikes of the tomato, and promptly control the flower king, and intelligently regulate the growth and nutrition matching, fill the vacuum of missing nutrients, and force excess return. Flows to the fruit to increase the level of fruit enlargement. After this inhibition, the tomato fruit can be the same size and the maturity is basically close.
3. When the tomato is deficient in potassium, the coloration is poor, the tendon rot is easy to occur and the yield is low. Therefore, after the flower is finished, when the fruit diameter exceeds 3 cm and begins to enter the expansion period, each time the water is poured per acre, the application is 10-20. Kg of potassium sulphate, combined with the use of light and nutrient film fertilizer, enhance photosynthesis capacity nutrients and chlorophyll, advanced environmentally friendly plants to increase fertilizer, increase production, color enhancement, leaf hypertrophy, dry stem strong compound membrane. It can help plants absorb a lot of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit. One-year benefits for one application.
4. When the tomato fruit is ripe, the fruit aroma factor can be sprayed to catalyze the synthesis of a hydrocarbon containing a benzene ring structure in the cell molecule, and the aromatic compound will continue to be released after the fruit matures. Aromatic taste. It can produce a lot of endogenous ethylene to make the ripe fruit surface bright and bright.

YESU Y41SE Fluorescent Detection Kit
1. The six-color fluorescence detection platform amplified 40 Y chromosome STR loci simultaneously, including 33 low mutation rate STR loci (mutation rate less than 1%) and 7 fast mutation loci (mutation rate more than 1%), a very low mutation rate Y INDEl
2. Y-str database is suitable for male pedigree screening and has strong individual identification ability. It contains all 35 loci which are required and preferred in Y database construction criteria.
3. Contains 12 mini-STR(loci with amplified length less than 220bp) to obtain more information from DNA degradation materials.
4, material compatibility, compatible with the direct amplification of most materials and the amplification of purified DNA
5. Rapid amplification, the theoretical amplification time was about 70 minutes.
