Summer and autumn high-yielding cultivation of tomato antivirus is a key measure in the production of vegetables. To promote the development of urban vegetable production, Sunjiaji Town of Shouguang City introduced this technology from the Plant Protection Institute of the Beijing Academy of Agriculture and Forestry Sciences in 1990. The technical highlights are as follows:
(1) Prepare basal fertilizer, fertilize the mutton to fully ferment and produce 10 thousand kilograms of tomatoes per mu. Pay attention to adding 10,000 jins of high-quality ring fertilizer (fresh chicken manure can also be used) or 1500-2000 pounds of cake fertilizer. The fertilizer should be under high temperature conditions. Decomposed fermentation, the fertilizer is wrapped in the pot before cooking.
(2) Selecting good varieties, carefully disinfecting them, starting from time to time, and direct seedlings and cultivating wheat bran.
The best variety is Maofen 802. Before sowing, use 10% trisodium phosphate to soak seeds for 20 minutes and rinse with water. Get up to 15 cm high and 60 cm wide, live broadcast every two lines, plant spacing 37 cm, 8-10 seeds per hole, 1 cm after the reconstructed earthworm cover 2-3 cm thick, to prevent drought and high temperatures. After the emergence of the cotyledon, the seedlings can be planted, and the velvet hairless plants can be separated, leaving many seedlings with velvet hairs, and 1-2 true leaves can be seeded.
(C) shade and rain, drought-proof pouring water, spraying CSC.
After sowing, shade coverings such as shading nets or sparse corn stalks can be placed on the shed film to prevent hot and drought. Pay attention to proper pouring of small water, so that the soil moisture content of about 16-18%, and pay attention to spray 3-4 times of 1000PPM chlormequat. The entire seedling period should avoid contact with rain and seedlings.
(D) the entire good branches, leaving enough ears, good fruits and vegetables. (single dry pruning, plastic rope hanging vines)
Tomatoes prone to nutrition, should pay attention to early removal, leaving 4-5 ears per plant, leaving 2-3 fruit per ear, should pay attention to the amount of 2,4-D flower (each 0.8-1 kg watered) , to prevent excessive use of drugs.
(e) Drug protection
First, the virus disease can be used 500 times the number of anti-virus one, virus A, phytosanitary three drugs alternately applied, once every 7-10 days, while spraying anti-viral drugs should pay attention to the prevention and control of whiteflies and aphids. The second is the application of Bamran nutritional protection liquid to prevent the occurrence of other diseases
(VI) Management in the middle and later stages can focus on the following six points:
A note of moderately mild temperatures. The ground temperature should not exceed 26 °C, and the temperature should not exceed 30 °C. If the temperature is too high, the temperature should be reduced by means of shading, water spraying, and ventilation.
B. Pay attention to timely top dressing and pouring water. Topdressing watering can not be too early, we must pay attention to the first ear fruit has walnut, two ear fruit has round date big, three ear fruit blossoming, top dressing and pouring water. Before this, it is advisable to use small water for 0;
In the early stage of C, in order to prevent drought, small water can be poured 1-2 times per month;
D Bamlan nutrient protection solution with chlorothalonil or carbendazim or thiophanate once every 10-15 days for disease prevention;
E late attention to insulation and increase carbon dioxide. If the temperature is too low to get late blight and blight, we must pay attention to keep the temperature at 25-30 °C, and avoid pouring too many times, reduce the temperature caused by the occurrence of low temperature, during this period to increase the number of people Carbon two or three months will help increase production.
F expansion fruit should pay attention to the use of Tianyuan liquid fertilizer, Chad, Lego America, Green Star, spray Po, rural people, K100, etc., spray 7-10 days once, spray 2-3 times. Late autumn tomato cultivation, in order to facilitate the post-insulation, in addition to paying attention to the above points, but also pay attention to the length of its arch shed more than 40 meters, and the use of high-quality non-drip agricultural film.
