1 Selecting good varieties This technique is suitable for cultivating celery varieties with high plant weight, high yield, and storage and transportation. Deyang chose the American (California) Belisae and Hong Kong sun brand celery for good quality.
2 timely planting seedlings
In the middle and early July, seedlings will be planted and the seedbeds will be filled with deep-gully high compartments so as to facilitate drainage. The 666.7m2 planted seeds will require 25-50g of seeds, 60 m2 of nursery beds will be needed, and high-temperature storms will be covered with shade nets. The seedling age will be 60-70 days (days).
3 Select soil, reapply base fertilizer, and select the sandy loam soil or loam soil with convenient drainage and irrigation in the deep trench high compartment. The former crop is rice. After the harvest from late August to early September, the rice will be filled with shallow water, and 1500kg of livestock and manure will be applied per 666.7m2. Spread 50kg superphosphate, potassium sulfate compound fertilizer 20-30kg, let it naturally dissolve in the shallow water, in the process of water infiltration, the applied fertilizer will infiltrate with the water, and distributed throughout Tillage layer. After applying base fertilizer, ditches with a width of 30cm or more will be dug around the plots. The width of the compartment is generally 3-4m, the depth of the ditch is 20cm, and the width of the ditch is 20cm. The earth removed from the ditch is laid evenly on the surface of the car. Due to the no-tillage technology, the land does not have to be dug or ploughed.
4 Before chemical weeding and 1 to 2 days before planting (days), use 66ml Gram-negative herbicide to spray water at 666.7m2, which can basically kill the weed plants that have been excavated and prevent sprouting of ratooning rice.
5 Perforated planting and making puncher: Use a flat steel with a thickness of 4mm, a width of 40mm, and a thickness of 1260mm to weld into a round steel ring and weld 8 conical punching teeth at the outer end of the steel ring (make the pitch of the planting holes on the ground reach 20cm About the requirement), the punching teeth are ground by a 2.5cm diameter rebar, the punching tooth length is 10cm, a rolling bearing is set in the middle of the ring, and 4 to 6 equally spaced steel bars are welded between the bearing and the steel ring. A handle is connected through the bearing to push the toothed steel ring to roll on the ground. In order to solve the problem that some of the plots have a relatively dry impact on the depth of drilling, one load carrier (or cargo platform) can be welded on each side of the steel ring near the bearing, and stones and other objects can be added to the load carrier to increase the weight. Make sure the depth of drilling.
Fix the hole: Using the hole puncher can increase the efficiency by more than 20 times compared with the hole digging and planting. When the soil is moist, use a hole punch to push or pull the hole in the vertical direction of the cabin so that the direction of the planting row is perpendicular to the direction of the box length, and the row spacing is 15 cm, that is, the row spacing of the planting holes is 1520 cm. If the soil is too dry and difficult to drill, it should be properly watered before applying the herbicide.
Colonization: Planting vigorous celery seedlings in the planting hole should be perforated with 1 car per carcase, in order to avoid water evaporation from the planting hole affecting the survival rate. During the colonization, the roots of the seedlings were vertically placed into the fixed holes, and then a small amount of moist soil was used to cover the roots. The roots were gently pressed to make the soil and the roots in close contact with each other, and then the root water was applied (without any fertilizer).
6 Applicable to top dressing planting after survival until the plant seal line generally top dressing 3 to 4 times fertilizer, decomposition of dry fecal residue can be mixed with compound fertilizer or compound fertilizer evenly applied to the line, but also can be used for composting manure dung water plus compound fertilizer or complex Mixed fertilizers are mixed and applied in the rows. After fertilization, shallow water is flooded to make the fertilizer water infiltrate into the soil. Generally, once the fertilizer is applied, the water is required to be fed once. After the fertilization, the medium to heavy rain is in urgent need of irrigation. Top dressing should be based on the principle of light weight and heavy weight. The top 1 to 2 top dressings should not exceed 20% of the total topdressing amount, and the 3 to 4 top dressings should reach 70% of the total top dressings. , The amount of the total fertilizer application of 10%. The total fertilizer rate of farmyard manure is 666.7m2 and can reach 3,000-4,000kg. The total fertilizer rate of N, P, K compound fertilizer or compound fertilizer can reach 66-70m2 and can reach 50-75kg. In order to improve the quality and yield of celery, it can be used for 2 or 3 times of foliar dressing in the middle and late stages of plant growth. Leaf tyrants, green leaf kings, foliar treasures, KH2PO4, etc. can be selected. Nine can also be selected before and 15 days (days) before harvest. Two water sprays are sprayed once, with a concentration of 20 mg kg-1. However, attention should be paid to the occurrence of hollow stems and defermented stems of celery, and more attention should be paid to the management of fertilizers and water.
7 Although herbicides were applied before weeding in the field, there was no follow-up killing effect on weeds re-grown after planting. For example, wheatgrass and amaphrodite were more harmful to live. Therefore, the survival of celery should be based on Weed herbicides were sprayed on the growth of weeds in a timely manner. It was proved that 666.7 m2 of 75 grams of pomegranate plus 45 ml of licorice could be sprayed on the field to spray water, which is very safe for celery and has a good weed control effect.
8 to strengthen the pest-free control of aphids in the entire growth period of celery can be damaged, can be used imidacloprid spray control. Liriomyza sativae also has damage, which may occur in individual years. Alternaria spraying, such as Lethburn, spot saccharine, and ephedrine, may be used.
During the breeding of celery, there are mainly damping-off diseases and root rot. The principle of comprehensive prevention, which is supplemented by the prevention and control of agriculture, should be adopted. Attention should be paid to the discharge of moisture from the seedbed to prevent waterlogging, and proper shading should be provided to prevent rain and sun exposure. At the initial stage of the disease, diseased seedlings were removed in a timely manner, and fungicides such as Guangkuiling, Lishujing, root rot spirit, and agricultural streptomycin were used for alternate spraying.
Leaf spot disease and virus disease may occur after colonization of celery, especially leaf spot disease. Heavily damaged leaf spot disease needs to be removed from the diseased leaves in order to prevent infection, and thiophanate-methyl is selected. , Kelu, cream grams, chlorothalonil plus water alternate spray. Virus disease prevention and control should first pay attention to eliminate fleas to prevent transmission of poison, and remove the diseased plants out of the field to destroy, the agent can use phytopathogenic spirit, anti-toxin, virus A and other spray control.
9 Timely harvest When the plants mature, they should be marketed in time according to the market conditions. The harvest period is generally from late December to mid-February. Premature harvest yield is low, but late harvest yield is high but stems are hollow and quality is reduced. When harvesting, the main root and fibrous root were cut off, and the old yellow leaf and diseased leaf were removed. Six to eight strains were bundled and put on the market.
Rice Field Celery No-tillage Standardized High-yield Cultivation Technique
Rice field celery adopts no-tillage standardized high-yielding cultivation techniques with high yield, good quality, low cost, good efficiency, and easy operation. Moreover, due to the realization of crop rotation, celery pests and diseases are relatively light, and the application of pesticides is less conducive to pollution-free. After years of exploration, we have concluded a set of relatively mature technological measures. The area of ​​promotion in our city has been expanding year by year. In 2002, the promotion area in Majing Town reached 270 hm2. The celery produced is mainly sold to Chengdu. , Mianyang, Chongqing, Deyang, Shaanxi, Gansu, Xinjiang, Qinghai, Shanghai and other places, 666.7m2 average output 4000kg (maximum output of 9000kg), total output 16.54 million kg, average price of 0.9 yuan / kg (maximum unit price 2.5 yuan / kg The average output value of 666.7m2 was 3,600 yuan and the total output value was 14,880,600 yuan. Using this technology 666.7m2 can save labor costs 70 yuan, and rice can increase production 25 ~ 50kg. The main technical measures are now reported as follows:
