Problems solved by technology

Therefore, no matter whether it is two-season or three-season planting, 50-65 days of land will be idle, but there are no suitable crops to plant, and the land resources have not been fully utilized. Moreover, old varieties of broad beans and peas are used, and the planting density should be high. , the knots are small, the growth period is long, the two are not suitable for interplanting, the yield and benefit are not high, and the market risk is relatively large

Embodiment 1

[0014] The first season, planting of new rice or early rice:

[0015] The first season of rice sowing and seedling raising time is half a month before the vernal equinox, and the growth period is 150 to 156 days. The grain seeds Gangyou 527, 11 Youhang 1, etc. are selected for sowing; 50 to 60 days later, they are cut according to the existing rice. The management method is to carry out daily management until the compound fertilizer is applied once 20 days before the harvest (that is, the heading stage), and the harvest is controlled to be completed from August 1st to 5th. The yield per mu is 600-700 kg, and it takes up 90-105 days of arable land (except seedling raising time).

[0016] The second season, planting of ratooning rice:

[0017] After the early rice is harvested, the ratooned rice begins to grow. Because the ratooned rice has a short growth period, it is difficult to achieve high yield. The present invention reapplies the decomposed and harmless farmyard manure d...

Embodiment 2

[0026] The first season, planting of new rice or early rice:

[0027] The time for sowing and raising seedlings of the first season rice is one week before the vernal equinox. The early rice varieties with a relatively short production cycle such as Shanyou 016 and Chengyou 89 with a growth period of 130 to 145 days are selected for sowing; they are cut after 28 to 35 days. The existing rice management method carries out daily control until 20 days before the harvest (ie, the heading stage) to apply a compound fertilizer once, and the harvest is controlled to be completed between August 1st and August 5th. The yield per mu is about 500-550 kg, and it takes 95-110 days of cultivated land (except for seedling raising time).

[0028] The second season, planting of ratooning rice:

[0029] After the early rice is harvested, the ratooned rice begins to grow. Because the ratooned rice has a short growth period, it is difficult to achieve high yield. The present invention reapplies ...

Embodiment 3

[0038] The first season, planting of new rice or early rice:

[0039] The time for sowing and raising seedlings of the first season rice is one week after the vernal equinox. The grain seeds with a growth period of 126-135 days are selected, such as Quanzhen No. 10, Jiahezhan and other early rice varieties with a relatively short production cycle. , after shifting and cutting, carry out daily management according to the existing rice management method, and apply compound fertilizer once 20 days before harvest (that is, the heading stage), and the harvest is controlled to be completed from August 1st to 5th. The yield per mu is about 450-500 kilograms, and it takes up to 96-105 days of cultivated land (excluding seedling raising time).

[0040] The second season, planting of ratooning rice:

[0041] After the early rice is harvested, the ratooned rice begins to grow. Because the ratooned rice has a short growth period, it is difficult to achieve high yield. The present inventi...

Abstract

The invention provides a method of four-season crop rotation of rice, broad bean and pea, in particular to two-season rice, one-season broad bean and one-season pea, totally four-season crop rotation; in the two-season rice, the first-season rice is a nascent rice and the second-season rice is a retooning rice; and the broad bean and the pea adopt an interplanting way to be planted after the retooning rice is harvested. The invention leads the land resources to be furthest utilized, not only is the rice yield increased by one season, but also the selected variety of the broad bean and the pea has high yield and good benefits and the two have good complementarity, thus not only saving fertilizer, pesticide, labor and lands, and simultaneously being capable of playing the role of preventing frozen injury caused by frost season of winter solstice.

Description

【Technical field】 [0001] The invention relates to the field of agricultural planting, in particular to a four-season rotation method for rice, broad beans and peas. 【Background technique】 [0002] For the tropical climate in Southeast Asia, affected by the oceanic monsoon climate, the climate is mild and pleasant, with rain and heat in the same season. In some areas, the annual average temperature is ≥19°C, the hottest month average is ≥27.5°C, the annual sunshine hours are 1950 to 2300 hours, the annual rainfall is 1000 to 1750 mm, and the frost-free period is ≥350 days. It is very suitable for the growth and development of broad beans and peas in winter and summer Autumn is also very suitable for rice planting. In order to make full use of land resources, traditional agricultural planting adopts crop rotation, that is, to select different crops in different seasons, and strive to keep the land idle. At present, the better planting method is two-season or three-season pla...
