Asparagus set of dwarf vegetables

Cultivation of asparagus requires a large row spacing. In the new planting asparagus field, due to the large spacing of asparagus, some dwarf vegetables can be interspersed between the rows, so that more than one year can be collected and the purpose of high yield and high efficiency can be achieved. The planting pattern is as shown in the figure. Cultivation Techniques: 1. Cultivation and Management of Asparagus 1. Selection of Varieties The current high-quality, high-yield varieties of asparagus include Mary Washington 500, Mary Washington 500W, California 72 (VC72), and California 873 (VC873). ), Lu Asparagus No. 1, Asparagus King (J2-2) and so on. When asparagus is cultivated, it can be selected according to the local conditions. 2. Sowing seedlings can be planted when the ground temperature is 5 centimeters below 5 centimeters. It is generally appropriate to sow in 5-6 months. According to the ratio of the seedbed to the field of 1:10-12, prepare the seedbed. Before sowing, fresh water can be used to remove unripe seed that floats on the surface of the water, and soaking for 12-24 hours with bird sprug 1000 times. Seeding bed 1.2-1.5 meters wide. Every 40 centimeters, open horizontal grooves, 2 cm deep. In the ditch every 7-10 cm, sowing 1 seed, covering fine soil 2 cm thick, and cover the straw 3-5 cm thick. For every mu of planted fields, use 400-500 grams of seed. When 60% of the seed emerges, remove the wheat straw. When the seedling height is 10-15 centimeters, 41 kg of urea and 3 kg of potassium chloride are applied per acre, and water is applied after spreading. Each month, top dressing is performed once, and the middle of September is the last top dressing. 3. Prepare 4,000 kg of organic manure per acre, deepen 25-30 cm deep, and then level the ground. For harvesting white asparagus, 1 trench is opened every 1.8-2 meters; for harvesting green asparagus, 1 trench is opened every 1.5 meters. The ditch is 30-40 cm deep and 50-60 cm wide. Each acre of the ditch is applied with 2000-3000 kilograms of circumferried manure, 30-50 kilograms of superphosphate, 10 kilograms of potassium chloride, 15 kilograms of ammonium sulfate, and mix with the soil. Another layer of 8 cm thick soil can be planted. Colonization is generally conducted from October to November or from the end of February to the beginning of March. When planting, cut the stalks of the shoots short, leaving 20 cm. The spacing is about 40 cm and the cover soil is 5-6 cm thick. After the combination of top dressing, the root plate was buried 10 cm deep underground. 4, field management cultivation of asparagus to apply more organic fertilizer. After harvesting each year, 1500-2000 kg of fertilizer is applied per acre, urea is 5-8 kg, 30-40 kg of superphosphate, and 15 kg of potassium chloride. The fertilizer is buried in the soil. In mid-August, 1,000 kilos of manure (or 10 kilos of urea), 30 kg of superphosphate, and 15 kg of potassium chloride were applied to the first batch of fertilizer per acre. During harvesting, there should be a certain amount of moisture in the soil, so that the stems can be drawn quickly and stoutly. In the rainy season, clear rows of sampans should be delivered. After watering or precipitating, it should be timely scratched in order to maintain the good ventilation of the soil. White asparagus was harvested, and soil was cultivated before spring stems were pumped. In the middle and early March, the soil is cultivated when the soil temperature is 10 centimeters above 10 centimeters. The depth of earth is 15 cm so that the green asparagus is stout. Harvesting begins 10-15 days after soil cultivation. After harvesting, the soil was immediately opened and the roots and stems were sun dried for 2-3 days. After the first top dressing, the ground was restored to the state before earth-cultivation. In order to prevent flooding and aeration, the soil around the plant may be slightly higher than the soil surface between the rows. 5. Diseases and Insect Pests Control The diseases of asparagus mainly include stem blight, brown spot, root rot and blight. In the winter, when the stems on the ground are withered, they should be pulled out, cleaned of litter, and burned away from the plot. Timely tillage and weeding. The rainy season should be drained in time to keep the soil dry and wet. When the young stems are unearthed about 10 cm high, spray 0.5-0.7% Bordeaux mixture, or 50% carbendazim WP 800-1000 times, or 75% chlorothalonil wettable powder 800-1000 times. Spray once every 10 days. Mainly prevention. Once the disease occurs, it can be sprayed with 64% antivirus 1000 times liquid. The underground pests of asparagus are mainly tigers, golden needles and cockroaches. The pests that damage the ground include tawny moths and thrips. For underground pests, poisonous baits can be used for trapping; for ground pests, pyrethroid pesticides can be used for control. Second, the management of sets of dwarf vegetables overwintering spinach, can be sown in mid-September to late November. At the time of sowing, 4 rows were planted between the rows of asparagus and the spacing was 1015 cm. Harvested in mid-March. Spring and summer broccoli in mid-March with a small arch nursery. In late April, asparagus was harvested, and it was planted between rows of asparagus with 2 rows and a spacing of 4040 cm. It was harvested from late June to early July. If harvesting green asparagus, broccoli sowing and planting time can be 20-25 days in advance. Broccoli can also be grown into dwarf kidney beans or dwarf vegetables such as spring cabbage cabbage, lettuce, dwarf tomato and fennel. The next step is to cultivate dwarf autumn vegetables such as purple cabbage, black-field carrot, raw radish, and garland chrysanthemum. In particular, the cultivation of green leafy vegetables can be timely adjusted according to the market's remaining situation to obtain higher economic benefits.
