RichFarm fight drought with you!


Does the weather have any impact on food planting?

It will definitely have an impact! Agriculture live at the mercy of the elements. It rains when it should rain, and it is dry when it should be dry, therefore, we can get the best food income. However, spring rains this year are less and generally drought.


Rice is in the critical period of seedling raising and transplanting, but some fields are still in a dry state. Rolling Greens suggest:

I、Transplanted Rice Crops

1.Drought-resistant seedlings。

Reduce water supply, make rice undergo moderate water shortage, promote the development of root system, increase root to shoot ratio, increase chlorophyll content, strong photosynthesis, and accelerate dry matter accumulation.

2.Increase potash fertilizer。

Potassium can promote the synthesis of RNA and protein, improve the hydration of the colloid; improve the carbohydrate metabolism of rice, increase the water content of the protoplasm, improve drought resistance, promote root development, and increase absorption capacity.

II、Sown Seedlings and Transplanted Rice.

1.With RichFarm, nothing will be wrong.

During the stage of seedlings with one leaf and one heart to three leaves and one heart, use 60 grams of RichFarm 1 powder 666m2 with 180L of water to spray the seedlings. RichFarm 1 has a very obvious promoting effect on seedlings, enhances the drought resistance of seedlings, and increases the elasticity of seedling age.


2.Dry land preparation & Dry seedling transplantation.

The field is leveled according to the dry field method. On the day of transplanting, the leveled dry field is fully moistened with water (100% water content in the soil), and then the seedling transplanter is used to dry seedlings immediately, and the soil is kept moist when the rice grows in a dry tube.

III、Rice Crops without Transplantation 

1.Switch to drought-resistant rice varieties.

2.Dry Direct-seedling Rice.

The field is leveled according to the dry field method. On the day of transplanting, the leveled dry field is fully moistened with water (100% water content in the soil), and then the seedling transplanter is used to dry seedlings immediately, and the soil is kept moist when the rice grows in a dry tube.

3.Seeding raising in advance

Choose early or mid-maturing rice varieties, quickly soak seeds in warm water to accelerate germination, heat preservation and moisturize to cultivate strong seedlings, and plant seedlings immediately when there is water in the field.


I、Select drought-resistant varieties 

1.Planting vegetable varieties with a short growing period, more extensive management, and drought-tolerant, such as water spinach, heat-resistant early radish, shallot, green amaranth, basella alba, pumpkin seedlings, etc.
2.For drought-tolerant vegetables (such as shallot), adopt the method of concentrated seedling cultivation, and choose cloudy day or evening transplanting to increase the survival rate.
3.Use plastic film, cover crushed straw or corn stalks to cover holes for transplanting vegetable seedlings.

4.Depending on the growth situation, the seedling period or the entire growth period shall be covered with shading nets.

II、Water saving

1.Cultivation and mulching to maintain moisture.

For the open-field spring vegetables that have not been cultivated with border mulch, they should be cultivated in time, loosen the soil and weeded, and irrigated in time. Use straw or mountain grass to cover the border to store water and preserve moisture, reduce water and nutrient consumption, and promote growth.


2.Topdressing scientifically to improve vegetable resistance.

Topdressing should be done early and deep; it is necessary to actively adopt wet application of chemical fertilizers, liquid fertilization and other methods to supplement soil moisture, promote the growth of vegetable roots, and enhance the ability of vegetable seedlings to absorb deep soil moisture.

3.Make full use of rainwater.

Do a good job in the prediction of soil moisture. According to the soil moisture content and the different water requirements of vegetables in different growth periods, determine whether vegetables are suffering from drought, listen to the weather forecast in time, and use rainwater for irrigation purposes without affecting the growth of vegetables.

III、Water saving technology

1.Low-pressure management irrigation technology.
Use PVC pipes instead of soil canals, and transport water from the water source to the field for irrigation through the concealed ground mobile hose for water delivery.

2.Sprinkler irrigation technology.

The water pump is pressurized, so that the irrigation water flows through equipment such as pipes or sprinklers to the air transforming into misty raindrops, which are evenly scattered in the field, and the vegetables are irrigated in a timely and appropriate amount. It is suitable for various terrains and soils, and has the advantages of water saving, labor saving, uniform irrigation, water and soil conservation, etc.

3.Microirrigation technology.

According to the water requirements of vegetables, the nutrients and water required by the vegetables are accurately delivered to the surface or soil near the roots of the vegetables through the low-pressure pipeline system and the special irrigation device installed on the final pipeline. It is divided into drip irrigation, infiltration irrigation, micro-spray irrigation and spring irrigation. It has the advantages of water saving, energy saving, and strong adaptability. It saves 15%-20% of water compared with sprinkler irrigation.

IV、改種Alternative crops

If the drought is severe and cannot be transplanted in time or the seedlings die due to lack of water, the previous crop should be cleaned up in time, and drought-resistant varieties should be selected, such as Guangmi No. 1 pumpkin, sweet taro pumpkin, Guangli powdery winter melon, etc.


Fruit trees such as lychee, longyan and chinese wampi are in their flowering and young fruit period. Citrus, bananas, and guava are affected by last year's frost and are in a critical period for new shoots and new leaves. Water shortage will directly affect the normal growth and flowering and fruiting of fruit trees. So we suggest:


Proper pruning work should be done, but remember that it is advisable to cut lightly instead of pruning a large number of branches. You only need to thin out the remaining, weak and dense branches to keep the canopy ventilated and light. Do not retract the tree canopy again during the high temperature and dry period, so as not to cause direct sunlight to damage the bark of the tree trunk and make it difficult to recover the tree canopy.


Making full use of the water conservancy facilities in the orchard, especially the use of water-saving irrigation techniques such as drip irrigation and sprinkler irrigation, can not only save water sources, but also ensure the water needed by the trees. If it does not rain for 10 consecutive days, it needs to be irrigated once, and the water volume is 40-50 liters per square meter of canopy each time。


樹盤覆蓋保水,通過淺鬆土切斷土壤中毛細根,減少水分蒸發;用稻草、雜草、綠肥或者地膜覆蓋可以有效的降低土壤水分的蒸發,保證土壤有充足的含水量Covering the tree trays to retain water, cut off the capillary roots in the soil through shallow loose soil to reduce water evaporation; covering with straw, weeds, green manure or plastic film can effectively reduce the evaporation of soil water and ensure that the soil has sufficient moisture.


Use white clover, bahiagrass, etc., sown 2-3kg per mu. It can store water, preserve moisture, reduce evaporation, improve soil fertility, and enhance drought resistance of fruit trees。
