1. Choose suitable varieties or different varieties of mixed plants to use Fengxiang, Mingbao and other varieties with high blooming rate, large amount of pollen, large and neat fruits, good coloring, weak sourness and less deformed fruit under low temperature conditions. Early autumn and autumn, All-Star and other varieties of pollen less produce more malformed fruit, should be equipped with planting Chunxiang, Dana and other varieties of pollination strains, in order to facilitate pollination and fertilization, reduce malformed fruit, increase the rate of large fruit.
2. Disease-free strong seedlings are selected for disease-free strong seedlings with developed root systems and strong disease resistance. The strawberries produced are large in size, high in yield, and of high quality.
3. Applying high-quality basal fertilizers to increase the quality of decomposed farmyard manure can provide sufficient nutrients for strawberry growth, flower bud differentiation, flowering fruit setting and fruit development, increase fruit size, and increase fruit sugar content and coloring degree. Each kilogram of ground chicken manure 2000 kilograms, ditch application and applicator combination.
4. Implementing crop rotation to avoid repetition of crop rotation can improve the disease resistance of strawberries and reduce the number of malformed fruits and pests and fruits. You can make full use of the open space cycle between sheds and sheds.
5. Increasing the light intensity of the strawberry 2 weeks before flowering to flowering will affect pollination, fertilization and malformation. Insufficient light during the fruit coloring period will cause the fruit to have a light taste and poor color. Under the premise of guaranteeing the temperature in the shed, the covered straw rake should be released as soon as possible. The north side of the greenhouse hangs a light curtain and uses reflected light to increase the light. Rainy days or snow days can be filled with incandescent lighting.
6. Rig cultivation and mulching with mulching can reduce the contact between the fruit and the shed film, enhance the sun's exposure to the fruit, reduce the incidence of gray mold, and promote fruit coloring. Film cover can increase ground temperature, reduce air humidity, and avoid direct fruit contact with the soil, which helps maintain fruit surface cleanliness.
7. Strictly control the appropriate temperature for the greenhouse temperature 22-25 °C during the flowering period, 8-10 °C at night, fruit expansion during the day 20-24 °C, night 6-10 °C. High temperature in the greenhouse will shorten the period of fruit development and make the fruit smaller.
8. Appropriate amounts of water, topdressing, flowering and fruiting period, suitable for drip irrigation. Insufficient moisture during flowering can lead to poor pollination and fertilization, resulting in malformed fruit. Insufficient moisture during fruit enlargement will affect fruit enlargement. During the fruiting period, 0.3% potassium dihydrogen phosphate solution should be sprayed continuously for 3-4 times.
9. Auxiliary pollination Pollination and fertilization is the root cause of malformation. The use of bee-assisted pollination can effectively reduce the production of malformed fruit. Generally, 1 box of bee pollination is put in each greenhouse during the flowering period.
10. Prompt control of pests and diseases During strawberry flowering, it is easy to induce deformity. If pests and diseases occur during flowering, they should be sprayed during periods of low bloom, and the beehives should be moved out of the greenhouse before spraying, and then returned to the greenhouse 1 week after application.
Antiparasitics are a class of medications which are indicated for the treatment of parasitic diseases such as nematodes, cestodes, trematodes, infectious protozoa, and amoebas.
Antiparasitic drugs are used to inhibit, kill or expel parasites in and out of animals. Most of the ancient antiparasitic drugs originated from natural plants and animals. Most of them have been eliminated because of their weak antiparasitic effect or high toxicity. The progress of modern science and technology has accelerated the development of pharmaceutical industry, and the variety and quality of antiparasitic drugs are increasing. At present, a large number of new, efficient, broad-spectrum and adaptive antiparasitic drugs have been developed. Antiparasitic drugs are usually divided into Anti helminth drugs, insecticidal drugs and antigenic drugs. According to the species of helminths parasitic on livestock, anti helminth drugs can be divided into nematicides, tapeworms and trematodes. At present, the commonly used antiparasitic drugs are: 1) nematicides: levamisole, tetraimidazole, thibendazole, mebendazole, thiadiazine (Kangchongling), tetrachloroethylene, ivermectin, etc; ② Anti tapeworm drugs: praziquantel, niclosamide (miezaoling), dichlorophenol, areca, etc; ③ Anti filariasis drugs: thioarsenamine sodium, iodothiazide, dichlorophenylarsine and Di, antimonol, etc; ④ Fluke repellents: Nitrazine, Nitrazine, hexachloro-p-xylene, praziquantel, etc; ⑤ Antigenic agents: chlorphenamidine, aminopropyl, benzoquinoline, shachongling nitrobenzamide (Qiuliling), etc; ⑥ Insecticides: trichlorfon, fenthion, phoxim, oxyphos, dimethamidine, etc.
