Abstract

The invention concerns a method for cultivating corn and like crops with similar morphology, whereby the seeds are sown along parallel furrows. Along each furrow are placed at regular intervals two seeds (10-11, 12-13, 14-15) at a slight distance from each other, thereby enabling to improve yield and days to harvest.

Description

Nouveau procédé pour la culture du maïs et des végétaux analogues . New process for growing corn and similar plants.
La présente invention a pour objet un nouveau procédé pour la culture du maïs et des plantes analogues.The present invention relates to a new process for the cultivation of corn and similar plants.
On sait que le maïs se sème généralement en lignes parallèles suffisamment espacées pour permettre le passage des engins de culture, une graine de maïs étant déposée par exemple environ tous les vingt cinq centimètres. Le semage du maïs s'effectue de manière conventionnelle à l'aide de semoirs à distributeurs rotatifs qui déposent les graines individuellement au voisinage d'un outil qui provoque leur léger enfouissement dans le sol.It is known that corn is generally sown in parallel lines sufficiently spaced to allow the passage of cultivation machines, a corn seed being deposited for example approximately every twenty five centimeters. The corn is sown in a conventional manner using seeders with rotary distributors which deposit the seeds individually in the vicinity of a tool which causes their slight burial in the soil.
L'invention est relative à un procédé de culture du maïs, qui par une disposition particulière des graines au moment du semage permet au maïs de se développer dans de meilleures conditions, ce qui entraîne une maturité plus précoce ainsi qu'un rendement supérieur.The invention relates to a method of cultivating corn, which by a particular arrangement of the seeds at the time of sowing allows the corn to develop in better conditions, which results in earlier maturity as well as a higher yield.
La présente invention a pour objet un nouveau procédé de culture du maïs et de plantes analogues, du type dans lequel les graines sont semées selon des rangs parallèles, caractérisé par le fait que le long de cha-que ligne, on dispose à intervalles réguliers un groupe de deux graines situées à faible distance l'une de l'autre, par exemple à environ 7 à 12 cm.The present invention relates to a new method of growing corn and similar plants, of the type in which the seeds are sown in parallel rows, characterized in that along each line, there is at regular intervals a group of two seeds located at a short distance from each other, for example about 7 to 12 cm.
Ainsi, alors -que les rangs de maïs sont espacés par exemple de 50 à 100 cm, cha-que groupe de graines est constitué par deux graines espacées d'environ 7 à 12 centimètres et de préférence de 8 à 9 centimètres, alors que les différents groupes sont placés par exemple à des intervalles de 25 à 45 centimètres et de préférence deThus, while the rows of corn are spaced, for example, from 50 to 100 cm, each group of seeds consists of two seeds spaced about 7 to 12 cm apart and preferably 8 to 9 cm, while the different groups are placed for example at intervals of 25 to 45 centimeters and preferably of
30 à 35 centimètres. D'une manière surprenante, il a été constaté que cette manière de semer le maïs a une influence importante sur la qualité de la récolte tant en ce qui concerne sa précocité que son rendement.30 to 35 centimeters. Surprisingly, it has been found that this way of sowing maize has an important influence on the quality of the harvest both in terms of its earliness and its yield.
En effet, lorsque selon l'état de la technique, les graines de maïs sont disposées à des intervalles réguliers de l'ordre de 15 à 20 centimètres, les plants de maïs se développent en disposant leurs feuilles de manière sensiblement régulière sur tout le pourtour de leur tige verticale.When, according to the state of the art, the corn seeds are arranged at regular intervals of the order of 15 to 20 centimeters, the corn plants develop by disposing their leaves in a substantially regular manner around the entire periphery of their vertical stem.
Au contraire, avec le procédé selon l'invention, les deux plants de maïs d'un même groupe se développent en se gênant mutuellement, ce qu fait que les feuilles des deux plants restent parallèles entre elles en se développant perpendiculairement au rang.On the contrary, with the method according to the invention, the two maize plants of the same group develop mutually annoying each other, which means that the leaves of the two plants remain parallel to each other while developing perpendicular to the row.
Ceci a pour effet de leur assurer un meilleur ensoleillement et une meilleure aération, avec comme résultat, une végétation qui se développe dans de meilleures conditions, qui conduit à une plus grande précocité et à un rendement plus important.This has the effect of providing them with better sunshine and better aeration, with the result, a vegetation which grows in better conditions, which leads to greater precocity and to a higher yield.
Les expériences qui ont été réalisées avec le procédé qui vient d'être décrit ont permis de constater qu'une variété de maïs, cultivé selon le procédé de l'invention arrive à maturité environ une à deux semaines plus tôt que le même maïs cultivé de manière conventionnelle, le rendement en graines du maïs étant supérieur d'environ 5 à 10 %. Ceci correspond à une amélioration d'environ 30 à 40 points de l'indice FAO.The experiments which have been carried out with the process which has just been described have made it possible to note that a variety of maize, cultivated according to the process of the invention matures approximately one to two weeks earlier than the same maize cultivated of conventionally, the seed yield of the corn being approximately 5 to 10% higher. This corresponds to an improvement of around 30 to 40 points in the FAO index.
Il est déjà connu de semer le maïs par poquets de 2 ou 3 graines disposées de manière aléatoire à des distances entre poquets de l'ordre de 25 à 40 cm, mais le positionnement aléatoire des graines d'un même poquet fait que les plants de maïs poussent de manière désordonnée dans toutes les directions ce qui ne permet pas d'obtenir les avantages inhérents à la présente invention selon laquelle les graines sont semées sur une même ligne par groupe de deux en étant séparées d'environ 7 à 12 centimètres.It is already known to sow maize in bunches of 2 or 3 seeds arranged randomly at distances between bunches of the order of 25 to 40 cm, but the random positioning of the seeds of the same pack means that the seedlings corn grow in a disorderly manner in all directions which does not allow to obtain the advantages inherent in the present invention according to which the seeds are sown on the same line in groups of two, being separated by about 7 to 12 centimeters.
Le procédé qui vient d'être décrit n'est pas limité au maïs et il peut s'appliquer également à la culture de toutes les plantes de même type telles par exemple que la canne à sucre.The process which has just been described is not limited to corn and it can also be applied to the cultivation of all plants of the same type such as for example sugar cane.
La présente invention a aussi pour objet un semoir monograines pour mettre en oeuvre le procédé qui vient d'être décrit, caractérisé par le fait qu'il distribue dans le sol selon une ligne, des groupes de deux graines séparés d'environ 7 à 12 cm, chaque groupe étant placé environ tous les 25 à 45 cm.The present invention also relates to a seed drill for implementing the process which has just been described, characterized in that it distributes in the soil along a line, groups of two seeds separated by about 7 to 12 cm, each group being placed approximately every 25 to 45 cm.
Conformément à l'invention, les graines sont d'autant plus rapprochées que le maïs appartient à une variété plus précoce. C'est ainsi qu'avec des variétés précoces ou irriguées, on peut placer les deux graines d'un groupe à environ 7 cm l'une de l'autre en déposant un groupe tous les 25 cm environ, ce qui donne une rangée dans laquelle les graines de maïs sont alternativement distantes les unes des autres de 7 et de 18 cm environ.In accordance with the invention, the seeds are all the closer together as the corn belongs to an earlier variety. Thus with early or irrigated varieties, we can place the two seeds of a group about 7 cm from each other by depositing a group every 25 cm, which gives a row in which the corn seeds are alternately distant from each other by 7 and 18 cm approximately.
Par contre, avec des variétés tardives, les graines peuvent être alternativement placées à des distances de 12 et de 30 cm environ, ce qui correspond au dépôt d'un groupe de graines environ tous les 42 cm. Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant à titre d'exemple un mode de réalisation particulier représenté sur le dessin annexé dans lequel :On the other hand, with late varieties, the seeds can be alternately placed at distances of 12 and 30 cm approximately, which corresponds to the deposition of a group of seeds approximately every 42 cm. In order to better understand the invention, we will now describe by way of example a particular embodiment shown in the accompanying drawing in which:
- la figure 1 représente une vue schématique de dessus de deux rangs de maïs cultivés selon la méthode traditionnelle,FIG. 1 represents a schematic top view of two rows of corn cultivated according to the traditional method,
- la figure 2 est une vue de dessus de deux rangs de maïs cultivés conformément à l'invention,FIG. 2 is a top view of two rows of corn cultivated according to the invention,
- la figure 3 est une vue de dessus de deux plants de maïs selon la figure 1 et- Figure 3 is a top view of two corn plants according to Figure 1 and
- la figure 4 est une vue de dessus d'un groupe de deux plans de maïs selon la figure 2 de l'invention.- Figure 4 is a top view of a group of two corn planes according to Figure 2 of the invention.
On a représenté schématiquement sur la figure 1 une vue de dessus de deux rangs de maïs obtenus selon le procédé habituellement utilisé à partir de graines semées à intervalles réguliers d'environ 15 cm.There is shown schematically in Figure 1 a top view of two rows of corn obtained according to the method usually used from seeds sown at regular intervals of about 15 cm.
Il est connu qu'en opérant ainsi, les différents plants de maïs 1,2,3,4,5 etc. se développent verticalement avec leurs feuilles régulièrement réparties sur leur périphérie en formant une sorte de haie continue ne laissant pratiquement pas d'espace entre deux plants de maïs voisins.It is known that by operating in this way, the various corn plants 1,2,3,4,5 etc. develop vertically with their leaves regularly distributed around their periphery, forming a sort of continuous hedge leaving practically no space between two neighboring corn plants.
On a représenté schématiquement sur la figure 2, une vue de dessus de deux rangs de maïs semés conformément à l'invention par groupes de deux graines disposées par exemple à 8 cm l'une de l'autre, avec un groupe environ tous les 30 cm, ce qui correspond à une même densité de graines à l'hectare que dans le procédé conventionnel de la figure 1.There is shown schematically in Figure 2, a top view of two rows of corn sown in accordance with the invention in groups of two seeds arranged for example 8 cm from each other, with a group approximately every 30 cm, which corresponds to the same seed density per hectare as in the conventional process in Figure 1.
Comme on le voit schématiiquement représenté sur la figure 2, les plants de maïs selon l'invention poussent en développant leurs feuilles perpendiculairement au rang, le plan médian des feuilles d'un même plant se situant perpendiculairement à la ligne du semis.As can be seen schematically represented in FIG. 2, the corn plants according to the invention grow by developing their leaves perpendicular to the row, the median plane of the leaves of the same plant lying perpendicular to the sowing line.
La manière dont les plants de maïs se développent verticalement avec les feuilles régulièrement réparties sur leur pourtour, dans le cas du procédé connu, est représentée en vue de dessus sur la figure 3.The way in which the maize plants develop vertically with the leaves regularly distributed around their periphery, in the case of the known method, is shown in top view in FIG. 3.
Au contraire, sur la vue de dessus de la figure 4, on voit comment les plants de maïs 12 et 13 appartenant à un même groupe de deux graines, se développent avec leurs feuilles situées essentiellement dans un plan perpendiculaire au rang de maïs, ce qui entraîne un meilleur ensoleillement et une meilleure circulation de l'air entre les tiges de maïs qui ont de ce fait une maturité plus précoce et une production plus abondante.On the contrary, in the top view of Figure 4, we see how the maize plants 12 and 13 belonging to the same group of two seeds, develop with their leaves located essentially in a plane perpendicular to the row of corn, which results in better sunshine and better air circulation between the corn stalks which therefore have earlier maturity and more abundant production.
Ce nouveau procédé de culture peut s'appliquer non seulement au maïs mais également aux autres plantes, telles que par exemple la canne à sucre, qui présentent une morphologie similaire et qui se cultivent en rangs en étant suffisamment rigides pour ne pas avoir besoin de tuteurs.This new cultivation process can be applied not only to corn but also to other plants, such as for example sugar cane, which have a similar morphology and which are cultivated in rows being sufficiently rigid so as not to need stakes. .
L'invention peut être facilement mise en oeuvre avec un semoir monograines modifié selon l'invention pour que son distributeur délivre environ tous les 25 à 45 cm deux graines espacées d'environ 7 à 12 cm. The invention can be easily implemented with a precision seed drill modified according to the invention so that its distributor delivers approximately every 25 to 45 cm two seeds spaced about 7 to 12 cm apart.
