Embodiment 1

[0053] The non-heading Chinese cabbage variety 'Qinglan' was used as the experimental material, and the rice printing cylinder (aperture 2.00mm, pitch 14.00mm) was used to print on glossy paper and matte paper, and the width of two kinds of seeding paper was fixed at 0.6m , cut it into a rectangular shape with a length of 1m, that is, the area of ​​each sheet is 0.6m 2 . In this experiment, 8 treatments were set up by random block method: rough surface paper + seed side up + no soil on the paper surface (T1); rough paper + seed side up + paper surface covered with soil (T2); rough paper + seed side down + no soil cover on the paper surface and paper back (T3); rough paper + seed side down + paper surface covered with soil (T4); glossy paper + seed side up + no soil cover on the paper side (T5); glossy paper + seed side Top + paper surface covered with soil (T6); glossy paper + seed side down, paper surface not covered with soil and paper turned back (T7); glossy paper + seed ...

Embodiment 2

[0061] Using rough paper, according to the plant density, produce two specifications of printing and sowing combinations, that is, combination A (aperture 1.1mm, hole spacing 30mm) and combination B (aperture 1.4mm, hole spacing 40mm), and investigate the seed fixation respectively.

[0062] Table 2 The number of seeds fixed on the sowing paper of the drum under different hole diameters and hole distances

[0063]

[0064] The results show that the number of seeds that can be fixed in each hole of combination A (aperture 1.1mm, hole distance 30mm) is 1, accounting for 56.27%, the number of seeds is 2, accounting for 28%, and the rest are small; combination B (aperture 1.4mm, hole distance 40mm) Due to the relatively large glue point, the number of fixed seeds is more evenly distributed, and 2 or 3 seeds fixed in each hole account for 69.60% of the total number of holes. In combination A, an average of 1.46 grains are fixed in each hole, which is converted to 1622 grains / m ...

Embodiment 3

[0066] The experiment was carried out in the glass greenhouse of Kunshan Vegetable Industry Research Institute (Kunshan Yuye Vegetable and Food Base) of Nanjing Agricultural University from September 5, 2018 to February 25, 2019. The strip substrate was used for cultivation, and the width of the cultivation substrate groove was 0.8m, while the width of the sowing paper is 0.6m, and the remaining 0.2m can be used for side row protection. The experiment was carried out in two crops in autumn and winter. In this experiment, random block method was adopted, and 5 treatments were set up, no cover (CK), covered with single-layer black sunshade net B1, covered with double-layer black sunshade net B2, covered with single-layer white insect-proof net W1, covered with double-layer white insect-proof net W2, 3 repetitions for each treatment, a total of 15 plots, each plot is 0.6m*1.0m, and the area is 0.6m 2 . The total test area is 12m 2 . After sowing with printed sowing paper, use...

Abstract

The invention discloses a non-heading Chinese cabbage printing sowing method which includes the steps: soil preparation; sowing paper material selection; seed facing setting; sowing density setting; sowing paper printing cylinder parameter setting; field covering mode selection; sowing paper sowing. The method effectively solves the problems that uniform sowing of a non-heading Chinese cabbage isdifficult, seed waste is severe, emergence rate is low, water and fertilizer consumption is high, product appearance commodity is poor, time and labor are wasted, cost is high, and waste is severe ina mechanical harvesting manner. Non-heading Chinese cabbages are uniformly sown, the emergence rate of seeds is increased, appearance commodity and mechanical harvesting adaptability of the non-heading Chinese cabbages are improved, the quality of the non-heading Chinese cabbages is greatly improved, growth cycle is shortened, diseases and insect pests are effectively controlled, water and fertilizer consumption and production cost are reduced, damage and waste in the mechanical harvesting process are reduced, the whole process is environmentally friendly and free from pollution and adopts tomechanization management, and the method can be popularized and applied to cultivation and industrialized production of the non-heading Chinese cabbages on a large scale.

Description

technical field [0001] The invention belongs to the technical field of cultivation of non-heading cabbage, and relates to a cultivation method capable of realizing uniform sowing of non-heading cabbage and adapting to mechanized harvesting. Background technique [0002] Non-heading cabbage, also known as Chinese cabbage and green vegetables, originated in China and is one of the most popular vegetables for the public. It occupies a high proportion of production and consumption in my country. Cabbage is rich in vitamins, proteins and trace elements, etc. It is an important part of human diet and an indispensable daily necessities. [0003] Non-heading cabbage has small seeds and is often sown by sowing. It is difficult to sow evenly during sowing, which can easily cause seed waste, low emergence rate, low uniformity, and uneven plant growth, which directly affects the appearance and poor commerciality of pakchoi products. The growth period of pakchoi is short, the cultivati...
