Embodiment Construction

[0019] Below in conjunction with the embodiment of "Huazhen" sweet corn, the present invention will be further described.

[0020] This embodiment includes the following steps:

[0021] 1) Choose sandy loam with good soil looseness and fertility and mix it with decomposed organic fertilizer in a ratio of 5:2, disinfect with chlorothalonil, and put it into 128 plug trays after placing for 10 days.

[0022] 2) Lay a layer of film on the ground, place the filled plugs on the film in sequence, dry the seeds for 1 day before sowing, pour the prepared plugs with foot water, and broadcast live by 1 dry seed per hole. Cover with 1-1.5cm thick fine soil, and then cover with a layer of film or sunshade net.

[0023] 3) When the seedlings emerge, control the temperature at 17-24°C and the humidity at 62-68%; when the seedlings grow to 2 leaves and 1 heart, lift the plug tray, and the main root of the corn seedlings has grown out of the water leakage hole at the bottom of the...

Abstract

The invention discloses a sweet corn lodging-resistance seedling raising and culturing method including steps of (1) applying fertilizer and preparing soil trays, (2) sowing seeds in the trays directly, (3) performing root excision after seedlings grow neatly, (4) performing ventilative acclimatization to the seedlings before transplanting, (5) planting green manure of vetch, (6) plowing the vetch into fields, and (7) transplanting, watering roots, ridging and then covering mulches. The method has the advantages of simplifying seedling raising and culturing processes, saving time and labor and the like, further, enabling roots of sweet corn to grow strongly, increasing growth speed of aerial roots, improving effective fertility of plant soil and soil permeability, reducing field weed effectively, improving quality of sweet corn effectively and increasing output by 15-20% as compared with that of the conventional culture method. By means of seedling root excision, soil humidity at roots is reduced, growth of lateral roots and aerial roots is accelerated, the root system total is increased by 10-25%, and thus, lodging resistance capacity of sweet corn is improved.

Description

technical field [0001] The invention relates to a no-tillage cultivation method for continuous cropping of melons and fruits, in particular to a no-tillage cultivation method for continuous cropping of melons, and belongs to the technical field of plant cultivation. Background technique [0002] Sweet corn, also known as vegetable corn, is a sweet subspecies of corn. Sweet corn is favored by consumers of all walks of life because of its rich nutrition, sweetness, freshness, crispness, tenderness and waxiness. It has high edible value and is widely used as a nutritious food for health care. [0003] The lodging of sweet corn is caused by external factors from the upright state to the inverted phenomenon. Lodging is an important factor affecting the yield and quality of corn. According to statistics, lodging leads to a decrease of 15% to 25% in corn yield. The annual loss of corn production due to lodging in my country is nearly 1 million tons. At present, with the continuou...
