In addition, a base fertilizer is firstly applied before spring stubble field planting and autumn stubble field planting, soil preparation is carried out after the base fertilizer is applied, 1-3 t of decomposed farmyard manure or 100-150 kg of bio-organic fertilizer is specifically applied per mu, 35-38kg of nitrogen-phosphorus-potassium ternary compound fertilizer is additionally applied, drip irrigation is paved while soil preparation is carried out in spring, finally mulching films are paved, three-layer covering technology is adopted in spring, namely, mulching films, small arch sheds and plastic sheds are adopted after soil preparation in autumn is finished. The suitable planting time in Jianghuai region is 2 months 28 days-3 months 2 days.
When drip irrigation is laid, drip irrigation pipelines are only laid between two rows of peppers, meanwhile, one end of the water delivery main pipe, which is positioned in the greenhouse, is connected with a pressurized water source, and an independent control switch is arranged between the water delivery main pipe and each drip irrigation pipeline. After the drip irrigation pipe is installed, the drip irrigation pipe is covered with a silver-black double-color mulching film so as to control humidity and keep moisture, prevent grass from warming, strengthen illumination at the lower part of plants, expel aphids and alleviate the occurrence of virus diseases.
Transplanting with soil during field planting, immediately watering the root fixing water and spraying sterilizing pesticide to ensure the normal and steady growth of the plant.
The early stage after the spring stubble field planting is mainly based on illumination management. The small arch shed is uncovered at about 8:00 am in sunny days, the illumination of watermelons is enhanced, the small arch shed is uncovered in advance for 0.5h in cloudy days, skirt films at two sides of the plastic greenhouse are lifted for ventilation at 9:00, the air temperature is low in the early stage, and the opening height of the films at two sides is about 30 cm; the later stage increases gradually along with the rising of the air temperature to enhance the ventilation effect in the greenhouse and supplement and balance CO 2 And prevent the damage to plants caused by the overhigh temperature. And covering a small arch shed at about 17:00, and closing the plastic greenhouse. And (5) observing the seedling-reviving condition of the plants at any time, checking the seedlings in time, supplementing the seedlings, and recording.
Pest control was noted at any time throughout the management period: irrigating roots with carbendazim hydrochloride, thiophanate-methyl and the like at the early stage of watermelon fusarium wilt, and preventing the roots from being changed by grafting of cucurbits or bottle gourds; spraying metalaxyl-manganese-zinc and metalaxyl wettable powder for treating pepper epidemic disease; the watermelon/pepper anthracnose can be sprayed for 3-4 times by alternately using zineb, thiophanate, carbendazim and the like; powdery mildew can be fumigated by using a chlorothalonil fumigant and a triazolone fumigant or sprayed with triadimefon. The white fly and aphid are trapped and killed by yellow sticky trap or fumigated by isoprocarb fumigant or sprayed by bipyridyl acetamiprid, beta-cypermethrin and the like; the yellow tea mites and the red spiders apply acarid, acaricide, lese, avermectin and pyridaben, etc.; the leaf miner is sprayed with abamectin, imidacloprid, spirotetramat, etc.
In the mode, the watermelon is manually pollinated in an auxiliary mode for about 4 months and 10 days so as to improve the fruit setting rate. The first female flowers (generally, the fruit to be set is malformed and small) are removed, only the 2 nd female flowers (less 3 rd) on the main vines and the side vines are pollinated, and when the pollination time is 7:00-10:00 a, only 1 melon is selected for each plant after fruit setting. The watermelon plants are cultivated by climbing the ground, the double vines are pruned, redundant side branches are cut off in time, the main vines are straightened among the pepper plants, and when the main vines of the watermelon reach the length of a cell, the center is picked in time. The side branches below the capsicum plant door pepper are removed at any time and all, so that the early-stage yield is increased, and ventilation and light transmission are facilitated. If the number of the row of the field planted peppers is 2-3, the side branches can not be removed due to the marginal effect, so that the time and labor are saved.
Harvesting fructus Capsici and ripe watermelon fruit at proper time after 5 months and 10 days, and packaging properly for marketing.
When the autumn field planting is carried out, the hole opening field planting is carried out in all afternoon or in all rainy days, the field planting of the peppers in autumn is carried out when the stubble is replaced as much as possible, namely, the field planting of the peppers in autumn of the original spring is carried out, and the field planting of the watermelon is changed from the outermost row of peppers in the original spring. The plant and the row spacing are 50cm, the row number ratio of the furrow field planting peppers with 2m width is 1:3, and the row number ratio of the furrow field planting peppers with 2.5m width is 1:4.
The root setting water and the sterilization insecticide are poured immediately after the planting, so that the survival rate is improved; the front-stage key point is that the sun is properly covered on sunny days, so that the seedling is promoted, and a 35% sunshade net is generally adopted for covering; while taking care of the greenhouse ventilation, preventing height Wen Zhuomiao. After seedling is recovered, the seedlings are cultivated once, squatting seedlings are squatted for about 5 days, and then water-soluble fertilizer mainly containing nitrogen is fully applied for 1 time (5-8 kg/667 m) 2 ) And (5) promoting the initiation of the plant. Watermelon vineWhen the length is 30cm (the height of the capsicum is about 25 cm), the cultivation is combined, and the nitrogen-phosphorus-potassium ternary compound fertilizer is applied for 20-25 kg/667m 2 The flowering period is to pay attention to ventilation and control the irrigation of the watermelon, and generally only a drip irrigation pipe of the pepper row is opened, and meanwhile, artificial supplementary pollination is carried out. Re-chasing ternary compound fertilizer 20-25 kg/667m in early stage of melon expansion 2 Watering and promoting melon, and the temperature is 25-30 ℃ in the daytime. The later temperature management is mainly to keep warm, the air release time and the size of the ventilation opening of the greenhouse are adjusted according to the air temperature condition in middle and late 10 months, and the day-night temperature difference is increased so as to facilitate fruit growth and watermelon sugar accumulation. Watering is stopped 7d before the watermelon ripens so as to increase the sugar content.
If the watermelon is cultivated by climbing, the two vines are pruned, and the operations of picking the core and the like are performed in spring; if the cultivation is carried out by adopting a bracket, ventilation and light transmission can be enhanced, the bracket is inserted when the length of the vines is about 25cm, the two vines are still pruned, the vines are immediately bound, and the core is plucked when the length is 2-2.2 m. Because the seasonal variation characteristics of the temperature and the illumination of the greenhouse influence, the growth of the autumn pepper plant is inferior to that of the spring, so that the side branches do not need to be removed. The whole growth period needs to pay close attention to the occurrence of diseases and insect pests, and the method is the same as that in spring.
The watermelon harvesting is relatively concentrated, the watermelon harvesting can be carried out in the market after about 10 months and 15 days, the peppers can also be harvested successively, but in order to obtain better benefits, the peppers can also be subjected to living fresh-keeping in the greenhouse, namely, the pepper fruits are not picked into a refrigerator and are stored together on plants (also called a plant bank), until the watermelon harvesting is carried out in the market in two periods (Yuan Dan-Chun festival), and when the minimum outside air temperature is close to 5 ℃, a small arch shed is also required to be arranged in the greenhouse so as to ensure that pepper plants and fruits thereof are not frozen.
In conclusion, the annual planting method of watermelon peppers adopts a three-layer covering technology in early spring, namely a mulching film, a small arch shed and a plastic greenhouse, field planting of watermelon and pepper seedlings is carried out in 2 months 28 days to 3 months 2 days, marketing of watermelon and green pepper fruits is realized in about 5 months 10 days, marketing of red peppers at the bottom of 5 months, and seedling pulling and shed cleaning before 7 months 10 days.
