Green bean cultivation technology for cotton
In recent years, due to the continuous expansion of cotton acreage, some farmers have been making full use of the growing period of crops in order to obtain better benefits, and began to use the intercropping model to increase planting efficiency. Nowadays, "Landspring" has passed, and the selection and preparation of cotton will soon be completed. The following is a selection of successful intercropping patterns in some of the main cotton producing areas in our province for reference by the majority of cotton planters.
The planting mode of cotton and mung bean interplanting is both simple and effective. Because mung bean plants are short and have a short growth period, root nodules also have nitrogen fixation, which neither affects the growth of cotton nor affects the yield of cotton. However, there are still some problems that should be paid attention to in the planting process. That is to select suitable varieties and scientifically determine the sowing date, so that mung beans can be better benefited without affecting the growth of cotton.
First, careful selection must use precocious, upright, high-yield, one-time maturity of mung bean varieties, such as: new varieties of green 7th, green 8th, old varieties of green 2 can be.
Second, timely planting through mung bean sowing period test concluded that the best sowing time for spring sowing mung bean should be in late April, this period can be planted with cotton, cotton can be divided into small and large rows, big lines 90 to 100 cm, small line 50 ~ 60 cm, this can improve the light permeability of cotton, is conducive to photosynthesis. After sowing cotton, one row of mung beans was sown in the cotton line. The spacing of green beans was about 15 cm, and 1 to 2 per hole. Over-slimming and denseness affected the yield of mung beans.
Analysis: If mung beans are sown in late April, before the cotton is ridged (July 15th or so), mung beans are basically mature and can be harvested at one time. If the cotton yield is not affected, the mungbeans can be collected for about 50 kilograms per mu. This period is also the highest price of mung bean in a year, because mung beans in the main producing areas of northeast and northwestern mung beans have not yet matured. This period is in midsummer and it is the period with the largest demand for mung beans in a year. The price of mung beans is relatively high. , can greatly increase the economic efficiency of farmers. If mung beans mature after July 15th, when the cotton starts to be ridged, it will affect the growth of mung beans, so that mung beans will not receive sufficient light, and it will just catch up with the rainy season. This will result in the phenomenon of falling flowers and seeds, and the grains will also be affected. , Reduced commerciality.
Third, timely harvest mung beans 80% of pods mature when harvested, promptly after harvesting drying, threshing and cleaning, grain moisture content of less than 14% can be stored in storage, and fumigation with aluminum phosphide to prevent soybean meal harm.
