JP2018019675A - Multiple branching seedling raising method of anredera cordifolia - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a rearing method of seedlings of Anredera cordifolia, which are difficult to branch and have only one stem elongated and leaves sparsely attached, with a yield expected to be the same as for conventional densely plated seedlings even if planted widely apart.SOLUTION: Before the main stem 1, the child branch, or grandchild branch of the Anredera cordifolia seedling reach 30 cm, the tip of the main stem, the child branch, or grandchild branch is cut leaving two to six leaves from the proximal region thereof, and by repeating an operation urging branching one to ten times, a seedling formed with a plurality of branches can be raised.SELECTED DRAWING: Figure 1

Description

  The technical field belongs to the method of seedling making in vegetable cultivation.

  Akazakazura is a climbing plant belonging to the family Crassaceae, and since it contains a lot of minerals, it has been attracting attention as a vegetable with a high health promoting effect in recent years, and its cultivation is increasing.

  Since seeds are not usually obtained in red-faced quail, vegetative breeding seedlings are cultivated by baskets, tuberous roots and cuttings, but since the top dominance is so strong that the seedlings are not branched, the seedlings are made of a single vine. Since branching does not occur easily even after planting, it has to be planted densely in order to achieve early high yield, and there is a problem that the burden of seedling cost and planting work is large.

  In Patent Document 1, for tomatoes that are extremely susceptible to branching, in addition to pinching at the upper part of the second true leaf at an early stage after seed germination, Although it describes how to make two tomato seedlings in which the second true leaf buds are elongated, in vegetative breeding seedlings using a basket, etc., and in branches and branches with strong top superiority It is not easy to grow the seedlings formed, and the method has not been established.

  Red-faced quail is hard to branch and has only one stem that stretches and leaves sparsely, so in order to harvest many leaves, it is necessary to plant seedlings closely, so there is a problem of requiring many seedlings. is there.

  Before the length of the main stem or offspring or grandchild branch of the vegetative propagation seedling of red-faced quail reaches 30 cm, leaves 2 to 6 leaves from the base of the main stem or offspring or grandchild branch, and the stem at the tip A seedling formed of a plurality of branches can be grown by repeating the operation of excising 1 to 10 times for one seedling.

  When planting seedlings formed from multiple branches, multiple branches extend, so that it is possible to increase the number of branches in proportion to the number of branches, and the required number of seedlings is reduced. The planting effort will be reduced.

  As in the case of raising seedlings in general vegetables, when makazaka's baskets and tuberous roots are buried in the medium under conditions of suitable temperature and humidity, in experiments so far, an effective integrated temperature of 16 ° C or higher is about 66 ° C until rooting. If the temperature reaches about 85 ° C. from the day of rooting to germination, it will germinate.

  After germination, one leaf spreads and increases at an effective accumulated temperature of about 14 ° C. Most preferably, the main stem is cut at the position indicated by 5 in FIG. Note that the term “extended leaf” refers to a leaf that has been opened, although a new leaf has occurred and is as small as about 1 cm after 2 to 3 days.

  Four days after the excision, buds begin to emerge from the leaflets of the fourth leaf and subsequently from the leaflets of the third leaf, and eventually two child branches as shown by 6 in FIG. 2 are formed. In the seedlings with strong momentum, buds start to emerge from the leaf buds of the second leaf, and three child branches are formed.

  If more seedlings are needed, remove the stem at the top of the second leaf, counting from the base of the child branch when each child branch has four leaves. After about 4 days, buds begin to emerge from the leaflet of the second branch of the child branch and then from the leaflet of the first leaf of the child branch, and eventually two grandchild branches are formed. If the same operation is applied to the other branches, a plurality of grandchild branches can be formed from any branch, so that seedlings formed with more branches can be grown.

  The timing and site of excision can be adjusted appropriately. If the excision time is advanced or the excision is performed so that the number of leaves to be left is reduced, the growth rate slows down and takes time, but it is possible to grow seedlings formed by a plurality of branches.

  This technique can also be applied to vine crops such as vineyards.

  The weak point of this technique is that it takes time to grow seedlings. Although the period required for seedling growth by the conventional technique is about 50 days, in this technique, the stem is excised at least once, so the growth is stagnant at each excision, and the seedlings formed by multiple branches are raised. About 75 to 120 days are required and the seedling price will rise. However, since the amount of seedlings required for planting is reduced from 50% to about 20%, the merit is greater than the increase in seedling price.

Claims (1)

  In the case where seedlings are nurtured by a red crested basket or cuttings or tuberous roots, the length of the main stem, offspring or grandchild branch of the seedling reaches 2 from the base of the main stem, offspring or grandchild branch before reaching 30 cm. A method for growing seedlings formed of a plurality of stems by repeating the operation of cutting off the stem at the tip of leaves to leaves 6 to 1 to 10 times per seedling.
