Abstract
The invention discloses a water and fertilizer management method in the seedling growing process of green Chinese onions. The method comprises the steps of watering management before emerging, water and fertilizer management at the one-leaf stage of green Chinese onion seedlings, water and fertilizer management at the two-three-leaf stage of the green Chinese onion seedlings, watering management at the four-leaf stage and later and watering management within seven days before transplanting. According to the water and fertilizer management method, watering and fertilization management is carried out at different growing periods of the green Chinese onion seedlings according to the changes of leaf areas of the green Chinese onion seedlings in the growing periods and photosynthesis parameters, the utilization rate of water and fertilizer is increased, and technical support is provided for a high yield of the green Chinese onions.
Description
Technical field
The present invention relates to agriculture seedling-raising technique field, particularly a kind of water and fertilizer management method in shallot seedling raising process.
Background technology
Shallot happiness is fertile, and requires nitrogen, phosphorus, potassium equilibrium to use. Growth is more to nitrogenous fertilizer requirement early stage, and stage needs more phosphorus, potash fertilizer. Pay special attention to using of phosphate fertilizer, scarce phosphorus can cause that plant strain growth is bad, production declining. And at present, traditional method for culturing seedlings is still outdoor the growing seedlings in land for growing field crops, in seedling raising process, be subject to natural environment influence larger, and field irrigation quantity and dose are unreasonable, liquid manure coordinated management lacks technical support, extremely unfavorable for yield potentiality, the raising liquid manure resource utilization of excavating shallot.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of water and fertilizer management method in shallot seedling raising process is provided.
For achieving the above object, the technical solution used in the present invention is: the water and fertilizer management method in shallot seedling raising process, said method comprising the steps of:
1) water before emerging: water water every day 1 ~ 2 time, water supply in media is controlled at the high wet condition of " lose open fire, finger pressure can water outlet ";
2) water and fertilizer management of 1 leaf phase of green onion seedling: onion seeds grows to first leaf after emerging, soil humidity is controlled at " semi-wet " state of " hold agglomerating, land loose ", during this period, sprays weekly marine alga microbial bacterial agent 15 ~ 30kg/ mu 1 time;
3) water and fertilizer management of 2 ~ 3 leaf phases of green onion seedling: moisturizing every other day, soil humidity is controlled at " semi-wet " state, and green onion seedling goes out after two leaves, sprays marine alga microbial bacterial agent 15 ~ 30kg/ mu, No. 6, green base 8 ~ 15kg/ mu, sprays weekly 1 time;
4) 4 leaf phases and later watering: mended a water every 2 ~ 3 days, the moisturizing time is controlled at 30 ~ 40min;
5) transplant first 7 days water, transplant and do not water for first 7 days, to carry out hardening.
Preferably, step 2) and step 3) in, the concrete steps that fertilizer sprays are as follows: first spray the moistening green onion seedling of clear water, then spray solution, finally spray clear water again, fertilizer is entered in matrix completely.
Preferably, step 2) and step 3) in, carry out spraying of fertilizer the morning that is chosen in fine day, dose is duty 0.1% ± 0.01%.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Shallot water and fertilizer management method of the present invention, according to the variation of green onion seedling leaf area in growth period and photosynthesis parameter, in the different time periods, spray liquid manure according to different ratios, adopt water and fertilizer management method of the present invention, compared with traditional booth border irrigation, liquid manure consumption has reduced 30% ~ 40%, compared with broad irrigation, has reduced 50%.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme of the present invention is further elaborated.
Water and fertilizer management method in shallot seedling raising process
1, water before emerging: water water every day 1 ~ 2 time, water supply in media is controlled at the high wet condition of " lose open fire, finger pressure can water outlet ";
2, the water and fertilizer management of 1 leaf phase of green onion seedling: onion seeds grows to first leaf after emerging, soil humidity is controlled at " semi-wet " state of " hold agglomerating, land loose ", during this period, sprays weekly marine alga microbial bacterial agent 20kg/ mu 1 time;
3, the water and fertilizer management of 2 ~ 3 leaf phases of green onion seedling: moisturizing every other day, soil humidity is controlled at " semi-wet " state, and green onion seedling goes out after two leaves, sprays marine alga microbial bacterial agent 20kg/ mu, No. 6, green base 10kg/ mu, sprays weekly 1 time;
4,4 leaf phases and later watering: mended a water every 2 ~ 3 days, the moisturizing time is controlled at 30 ~ 40min;
5, transplant first 7 days water, transplant and do not water for first 7 days, to carry out hardening.
More even in order to ensure water spray, fertilising,, adopt water-fertilizer integral equipment here, make fertilizer management and the water management can simultaneously operating.
Concrete, this water-fertilizer integral equipment comprises master control system, the multifunctional motor-driven water pump of being opened by master control system control and fertile pump, valve, filter, irrigation pipe, rotatable " L " type damping torrent distributing sprinkling irrigation sprinkler head and be distributed in the multiple Node Controllers in each booth region.
Facility pipeline mounting means is bypass type, takes to note fertile pump when fertilising, directly mixed fertile in pipeline. Service conduit divides three grades. The outer immersible pump upper pressure limit of canopy is 0.4Mpa.
Shower nozzle used interval 2m is uniformly distributed in the irrigation pipe of seedbed height 2m, this shower nozzle comprises corresponding giant and small nozzle, can form a kind of effect of breaing up torrent, makes the well atomization of moisture of ejection, seedling easy to break is evenly sprayed at seedlings nursing plate, even if also can not be bended.
In step 2 and 3, the concrete steps that fertilizer sprays are as follows: first spray the moistening green onion seedling of clear water, then spray solution, finally spray clear water again, fertilizer is entered in matrix completely. Adopt this order to carry out spraying of fertilizer, can guarantee that fertilizer enters in matrix completely, can't cause burning seedling to green onion seedling.
While spraying fertilizer, carry out spraying of fertilizer the morning that should be chosen in fine day, dose is duty 0.1%, and fertilizer excessive uses that can to cause crop to burn seedling lethal and environment is caused to certain pollution.
Water and fertilizer management method of the present invention, compared with traditional booth border irrigation, liquid manure consumption has reduced 30% ~ 40%, and compared with broad irrigation, liquid manure consumption has reduced 50%.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
