Abstract

The invention discloses a cress seedling evening method. When cress flowering stalks are seeded, newborn seedlings grow to the length of 15-20 cm, and the base parts of the newborn seedlings have 3-5 joints, the newborn seedlings are mowed near to the ground, a zone with dense seedlings is heavily mowed and 1-2 joints are reserved; a zone with sparse newborn seedlings is slightly mowed and 3-5 joints are reserved; reserved lateral buds are facilitated to grow; in a zone remarkably lacking seedlings, mowed newborn seedlings from the zone heavily mowed are uniformly scattered on the zone lacking seedlings. If second-time newborn seedlings in bud are still remarkably uneven, the newborn seedlings are mowed once again according to the standard, as a result, the seedlings in field can be better distributed evenly, 'dragon head seedlings' likely to be produced can be removed, and labor is saved.

Description

The even seedling-growing method of a kind of Chinese celery

Technical field

The present invention relates to the even seedling-growing method of a kind of Chinese celery.Belong to agricultural (vegetables) culture technique field.

Background technology

Chinese celery is generally sowed with female stem aging in seed field, " wipes out it without bud or the top of only having tiny axillalry bud slightly." female stem of vernalization or not vernalization is evenly discharged, be commonly called as seeding, but produce the upper stem section that generally female stem is cut into the 30cm left and right, broadcast sowing equably field.", because sprout growth seedling after seeding is difficult to uniformity, must be adjusted by even transplantation of seedlings.Make that full field is every has seedling 2-3 strain apart from 10-12cm, and, to suitable dark the inserting of too high seedling, impel growth neat." (Zhao Youwei chief editor. Chinese aquatic vegetable. Chinese agriculture publishing house; December in 1999 the 1st edition: 133-134) implement ealy maturing culture in summer or early autumn; also will strengthen population density; and still be in generative growth phase because of the female stem terminal bud of high temperature season; terminal bud should be removed before sowing; otherwise terminal bud can continued growth, or bloom in top, no longer upwards growth, or crooked growth like dragon flying around, form " leading seedling " that the peasant is commonly called as and upset colony.Every mu of field of even transplantation of seedlings is generally wanted recruitment 2-3, wipes out female stem top and slightly with operations such as cutting up with a hay cutter disconnected female stem, also need spend a certain amount of recruitment, under present labour's intense situation, must seek more saving of labor's new cultivation technology.

Summary of the invention

, in order to overcome above-mentioned defect, the invention provides the even seedling-growing method of a kind of Chinese celery.

Method of the present invention, the Chinese celery scape after planting, when newborn seedling reaches 15-20cm, base portion 3-5 joint position arranged, adopt near the ground seedling to be cradled.Find that there is the female stem terminal bud that keeps the reproductive growth state, first its terminal bud is cut off, then implement near the ground cradling.Particularly, comprise the following steps:

(1) in the sowing of female stem, seedling sprouts and grow to 15-20cm, when base portion has 3-5 to save, at the seedling basal internode, cradle.

(2) find that there is the female stem terminal bud that keeps the reproductive growth state, first its terminal bud is cut off, then by above-mentioned standard, cradle, effectively remove leading seedling.

(3), if the seedling that again sprouts is still obviously inhomogeneous, can again cradle to the seedling that sprouts even by above-mentioned standard.

In said method, for making again the seedling that sprouts even, while cradling, seedling keeps than Mi Chu that the 1-2 joint heavily cradles, rarer place keeps the 3-5 joint and gently cradles, and inspires the lateral bud growth of toothing, and the seedling colony uniformity of sprouting is better so again.

If the zone that obviously is short of seedling is arranged, can with near cradle the seedling of cutting off in heavier zone and be sprinkling upon equably the zone that is short of seedling.

(4) this method can obviously be saved even seedling recruitment.

Description of drawings

Fig. 3 sprouts the rice shoot colony that forms again after cradling.

Embodiment

(1) 2013 year 6-7 month implemented in Chinese celery base, Zhu Lin town, Jintan City.June 2 took out the female stem of Chinese celery is cut off from base portion with reaping hook in seed field after, directly female stem was broadcasted sowing equably in field (Fig. 1);

(2) June 21, the seedling major part of sprouting has grown to the 15cm left and right, field still has the female stem terminal bud of part to be in the reproductive growth state and bloom (Fig. 2), cradled on request with the seedling of sharp reaping hook to field June 25:, for the closeer zone of seedling, generally keep base portion 1-2 joint; The zone that seedling is rarer, keep base portion 3-5 joint.Bloom or the crooked seedling that grows for top, should first its top slightly be cut off, then by above-mentioned requirements, carry out near the ground cradling., if the zone that obviously is short of seedling is arranged, cradle the seedling of cutting off in heavier zone near inciting somebody to action with reaping hook and be sprinkling upon equably the zone that is short of seedling.An experienced operator can process 5-8 mu field in one day, had obviously improved labor productivity.

(3) July 28, again sprout the rice shoot colony uniformity (highly, density) better (Fig. 3) that forms after cradling.

Claims

1. the even seedling-growing method of a Chinese celery is characterized in that: the female stem of Chinese celery after planting, newborn seedling reaches 15-20cm, when base portion has 3-5 joint position, at the seedling basal internode, cradles, the lateral bud that inspires toothing is grown;

(2), if the seedling colony of again sprouting finds that there is the female stem terminal bud that keeps the reproductive growth state, first its terminal bud top is cut off, then by the standard in step (1), cradle.

2. method according to claim 1 is characterized in that: while cradling, seedling keeps than Mi Chu that the 1-2 joint heavily cradles, rarer place keeps the 3-5 joint and gently cradles, and inspires the lateral bud growth of toothing; , if the seedling that again sprouts is still obviously inhomogeneous, by above-mentioned standard, again cradle.

3. method according to claim 1 and 2, is characterized in that:, if the zone that obviously is short of seedling is arranged, with cradling the seedling of cutting off in heavier zone, be sprinkling upon equably the zone that is short of seedling.
