RU2004123C1 - Fodder crop seeds harvesting method - Google Patents

Description

tami in parts, in 2-3 doses with a gap of 1 day.

Under production conditions, the espartsite massif, after desiccation, must be threshed to a straight line at a cut height of 30-35 cm so that the thinnest part of the stalk with seeds gets into the combine for threshing.

With this harvesting technique, seed yield is increased by 25-30%. The resulting seed heap has optimal moisture, is not self-heating, and does not cause a decrease in germination energy and seed germination.

After cleaning and sorting, the moisture content of the heap is reduced to 9-10%. Verification of the sowing qualities of sainfoin harvested in 1990 in the 3rd brigade of the Gorky collective farm in the Kuschevsky district of the Krasnodar Territory using the old and new technology showed the following results (see Table 1).

Sudan grass: the existing harvesting technology provides for the mowing of plants (when they sprout 2-2.7 m) with mass ripening of seeds on a panicle of the central stem, SK-5 combine with ZhRS-4.2 header or incomplete capture by the ZhVN- header 6. After 7-10 days, in good weather, the seeds reduce moisture to 15-20%, and leafy stems 25-30-40%. However, when threshing the roll with the SK-5 combine, no conditions are created for high-quality mass separation. As a result, up to 20-25% of the seed is lost. They, together with the leaf-stem mass, go into the plunderer.

Seed heap is fed to a current with a moisture content of 15-18%, i.e. requires immediate sorting and drying; otherwise, after 3-5 days, germination energy and seed germination are reduced. (After all, a heap is prone to self-heating).

To address these drawbacks, the following is proposed.

With a moisture content of the bulk of seeds of 32-35%, desiccation is necessary. Preparations and their dosages are similar to those used on sainfoin. Chemical drying in a given crop is performed better by plane or helicopter. After 5-7 days, a direct threshing of the grass is carried out with Don-1500, SK-5, SK-6 combines with a maximum cutting height, which makes it possible to mow mainly the panicle with part of the stem.

The remaining stems of the Sudanese grass are scored and chopped after a double pass of the BD-10 disc harrow and smelled.

The results of the production audit carried out in 1989 on the Victory collective farm of the Kushchevsky district of the Krasnodar Territory are presented in Table 2.

The cost-effectiveness of increasing the quantity and quality of sainfoin and Sudanese grass seeds during desiccation is presented in Table 3.
